I'm generating reports on the fly using the great SpreadSheetGear tool. At first things were great because the reports were simple and done in under 1 second. Now I'm at more complex reports and they are taking about 30 seconds up to 1 minute. This isn't a problem, we just throw up an activity image and let the user wait, fine by us.
The problem I've found is when two users come to the site.
User 1 comes to the site
User 1 runs a report that takes 30 seconds.
User 2 comes to the site
User 2 waits until user 1 report is done then the page loads.
The report running for User 1 hangs up the site until it's done. What is going on and how can I fix this?
We have been using the same pages for many years. All of a sudden it is taking the classroom educators 23 minutes to go from page to page. We hired an individual and they find nothing wrong with our firewalls and security system.
There are no loops in our code or referring to databases.
We also hired a Microsoft consultant from Washington State and she recommended that we stay with asp Classis because we have over 27,000 pages.
Whare can I find the forum for asp classic. I need to find out why it is taking so lon to go from one page to another. Our Web Site programmers are getting pretty disgusted.
I wrote a test page that does a bunch of busy work in a method called at page load. This process as I have it now takes around 12 seconds.
If I try to load another page while the first long running page is loading, this second page doing nothing except writing out a world, it doesn't load until the first long running page is finished.
Why is this the case? I would think IIS would be able to handle multiple concurrent connections, it seems crazy that one long running page would stop every other page in the application from loading. I must be missing something or not understand how IIS works.
I would think multiple independent requests would be spawned on different threads. Is this only the case if the requests are from different sessions entirely? Are all requests from a single session bound to a single thread?
I've developed a web application to accept video file uploads and then pass them to a backend service on an external server. The application runs without error on the visual studio debugging webserver, but once on a production iis 6 or 7 server, yields a timeout error at about a consistent amount of time into handling a large upload. Specifically, it errors in the middle of transferring the video file to the external server, once the application has successfully received it from the client. I'm aware of several timeouts to be configured related to the problem, and have done so. The application's web config has been tested with one or both of the following settings
<system.web> <httpRuntime executionTimeout="9999999" maxRequestLength="2048000" /> </system.web> and <configuration> <location path="default.aspx"> (the page at issue that's timing out) <system.web> <httpRuntime executionTimeout="9999999" maxRequestLength="2048000" /> </system.web> </location> </configuration>
And within the initialization of the webrequest made to the external server to send the video received from the client browser:
So with the execution time limits on both the webform as a whole and the connection made to the external server, I'm at a loss for what timeout is left unconfigured, or how to determine such, when I continue to get the following error: Unexpected error executing Brightcove Upload:...........................
We've recently been experiencing an SSRS (SQL Server 2008) report displayed in an ASP.NET web application using the ReportViewer control (Microsoft.ReportViewer.WebForms,Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a) hanging when rendering a report with over 100 rows and causing Internet Explorer (6, 7, 8) to use 100% (of one core) of CPU.The report renders quickly in Firefox (and doesn't use high CPU).
Visual Studio 2010 hangs up more tha 20 times in a working day. I'm thinking of going back to 2008 but that is such a hassle. Mostly it hangs when debugging starts and when I open a xaml file. I'm doing silverlight/WCF development.I have HP I7 laptop, 8gig, windows 7 64bit.
When I try to start my application in debug mode (F5), 1 out of three times IE opens with a blank screen, and Visual Web Developer says it cannot start the application. Sometimes it also says "Element not found". I can only shut down IE by using the task manager.
I'm having a simple ASP.NET application hosted on my local IIS6, under Vista.It contains a button that when I click I execute a piece of code for recognizing the text in a WAV file (using the System.Speach.Recognition.SpeechRecognition class) and display the text in a label.
The code works great on a desktop application, and it almost works on the web one... I say almost, because if I debug, I can see that the recognizer returns the correct text from the WAV, I can see that I am finishing the handler for the button click with no error, but nothing gets displayed in my page, and the page appears like loading... it's hanging, or something... No errors, no timeout, nothing. Just loading...
I don't know if this detail helps, but in order to make the piece of code that was already working on the desktop application work on the web application, I had to set the identity of the ApplicationPool of my application to LocalSystem (security breach, I know). Otherwise, I would have received a Access Denied error (0x80070005(E_ACCESSDENIED)).
We have an ASP.NET 3.5 application that has been in production for over a year. Our last release was a couple of months ago. We use CSS for styling and application of background images to divs and such. The server is Windows 2003 with IIS.
Suddenly, this week, we have had reports from some users that the page seems to hang up while loading. The status bar was showing the name of a background image used in the page main area (assigned in CSS). At our office, some of us could recreate the problem, while others could not. IE6 and Firefox do not seem to be affected, only IE7/8. Running Fiddler on an affected machine and trying to see what was happening with the requests seemed to make the problem go away (while running through Fiddler, it returned when not). Hitting Refresh on a hung load often made the page load just fine.
I checked the background image, and even replaced it with an archived copy. No joy. We re-deployed the app from our production source. No Joy. We restarted IIS and eventually rebooted the whole server. There are no unusual entries in the event logs, the app logs or the IIS logs. Finally, I removed the image entirely and re-styled the page not to use a background image. That solved the problem at least for now.
However, we have reports of other images "hanging." The images are PNGs, but I have heard some rumors that sometimes a GIF hangs, but I have no screenshot to confirm.
This just started happening "out of the blue." There have been no releases or updates applied to the server recently. We even checked updates on clients to see if a recent Windows Update might have caused this on the client, but there was nothing updated within the last couple of weeks.
I have a development box running Win7 and VS2010. A User Acceptance Testing server running Windows Server 2008 / Sql Server 2008 and a Live server running Windows Server 2008 / Sql 2008.
When doing development I connect to a development database on the UAT server.
I have a problem that only occurs when I change the connection string to point to the database on the Live Server.
So, before I start describing the problem - the app works fine in development and when published to the UAT server - but there is a problem when I either publish it to the live server or, whilst on my dev box, point the connection string to the live database.
Here's an example.
I have a page with a gridview on it. In each row of the gridview there is a drop down list. All calls to the database are done through a Data Access class.
Say I have a function on an .aspx.cs page called GetDetails().
In this - to populate the Gridview I'll have something like ...
I am using update panel and Tab container of Visual Studio 2008 (VB .NET) in my pages, but in one of the pages I am having a problem. The page structure is something like a List Tab and Details Tabs. On page load LIST tab is visible and other tabs invisible. User clicks on a record and click Modify button. Then List tab gets invisible and other details tabs (4 of them) visible. Here I have OK (to save data) and CANCEL (do not save the data) buttons. On which the list tab again gets visible and other tabs invisible. Now here I am facing a problem. I have same functionality on my other pages also. But in this page when I click on OK or CANCEL button my application hangs after END SUB. My whole click event of both the buttons runs fine up to END SUB but after that the problem starts.
Developing a website in ASP.net. On the development site all is working fine.We decide to publish the site using visual studio 2008's publish mechanism.The publish goes flawless.When we go to the live site, it hangs anywhere from 2 minutes to 30 minutes before it starts serving pages.All other sites on the same server seem to work fine.If we reboot the server it starts serving pages right away.It is not a programming issue, as once the site kicks in all seems to work fine.VS 2008, .NET 3.5, On both IIS 6.0 and 7.5
I have a website that seems to be Ok in Mozilla but when I access some pages in IE (mostly the ones where it has to contact a web service) the page hangs. If I refresh and then click the same button again, it seems to work fine 90% of the time. As mentioned, the same features work flawlessly in Mozilla.I am not really sure where I need to go to start debugging this but does anyone have any ideas on a cause?The website is hosted on my machine which is running on localhost using IIS7 on Vista and the web service is hosted in the same place. (So all it should need to do is contact itself). Its is an ASP.NET website running framework 2.0 (something)
I have a Main page containing links to five other pages. each page has a button which does some job using Thread. Problem is when i open a window from main page and click the button, The Process starts but if now i want to open another page from main window it doesn't load untill that previous page loads fully(when thread ends). I am not using any session variable on my page.
I have a website installed on one of our sales guys laptops and am having issues with the website hanging if left for 2 minutes. This doesn't happen on my dev box, my live machine or the other sales guys machine.
The website will hang. It's not just limited to this page, it will happen on all pages when I leave it for more than 2 minutes and then try and process a page that calls back via button or drop down ect. I have checked the IIS settings of the machine and everything seems the same as the other sales guys machine who is running the same version of the site.
Here are the specs:
Dev Box: asp.net 2, windows server 2008 64bit
Live Box: asp.net 2, windows server 2008 64bit
Working Sales Guy: asp.net2 windows 7 64bit
Broken Sales Guy: asp.net 2 Windows vista 32 bit (the only thing I can see different is windows version)
EDIT: For more information, if I stop the website from trying to load while it hangs, clear my history for the last hour and then refresh, the page comes back fine.
EDIT2: I have just spat out some debug information and it seems it doesn't even go into the post back I need.
EDIT3: This doesn't seem to happen when using Chrome but does when using IE and Mozilla.
ASP.NET MVC 3 was released on Jan 13, 2011. I was able to install it on my XP SP3 workstation. But, when I opened an MVC C# project, VS 2010 hangs. I have repaired VS 2010 and Framework 4.0 with no luck. The issue was resolved after uninstalling VS 2010 SP1 Beta. Does anyone know if ASP.NET MVC 3 works with VS 2010 SP1 Beta?
I have a server running Windows Server 2003 R2 Standard Edition (Service Pack2) and our IIS server is hosting about 20 different asp.net websites. I've never noticed this in the past, but when I debug an application and it stops at a breakpoint, the other websites hang as well. If I try to go to any of the other websites, then I just get a while page that's loading until i pass the breakpoint or I stop debugging.Does this have anything to do with application pools and if so, how do i fix it? Or if it does not, any ideas on how to fix this issue? I find myself debugging my apps often and I can't bring down all other applications when I do it.
I have a web application which hangs after clicking a checkbox which is set to autopostback. This checkbox is supposed to do some process.
When I did the breakpoint, the application does not go to the On_PageLoad event but goes directly to the On_Unload event. After that, it hangs. It does not go to the On check changed of the checkbox.
Here are the events that are only called after the checkbox has been ticked.
I'm currently in the process of deploying my C# website. In the development IDE everything works fine but when i deploy to ISS 7 some of the pages work fine but others will just randomly hang. Ive been using the tracing utility and debug code to see where the problem is occurring. This is where it gets weird. If I turn on the tracer and set the pageoutput to true it works as fast as it does in the IDE without the hangs but displays all the tracing information. If i set the pageoutput to false and leave the tracer on, it will return to having the same problem. Ive put time outputs through the system and everything is running through quickly. So im at the point now where if i have the tracer displaying on the website there is no problem. But if i don't display the tracer the problem occurs and i cant see the logs to pinpoint it. The problem is occurring after EndRender. Sometimes it loads the top of the page and then hangs. The pages do complete but can take up to 10 seconds. . The same problem is happening in both IE and firefox.
have a web application hosted on Windows Server 2003 SP2 with IIS 6. I use ASP.net Web Forms and ASP.net AJAX.Some times, when clicking on a button to perform an action the web application does bot respond to the user.After debugging i have found that ErrorSys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 413
I have created a SSRS report with a tablix and some external images(both .png/.gif). This report is going to be generated for different Languages, so i have used Arial Unicode MS.
I render the report as Attachment on click of the print button (I flush() the byte[] array from the SSRS Render function as Respone on to the page). Report gets generated properly with open/save/cancel. But on click of OPEN the abode reader gets hanged. I tried to save the report and open, but no luck.
Size of the pdf is less than 150 kb. I have Abode ver 9.4 and SSRS 2008.
I'm having a problem with file streaming where this file is a video that is streamed to a FLV player.
Essential components for understanding the problem:
- An asp.net page called Viewer.aspx that has de FLV player incorporated in the HTML.
- An asp.net page (It could be an http handler but in this case it's not) called Downloader.aspx that gets a flv file from somewhere on the web and writes it to the Response Output Stream.
Everytime Viewer.aspx is called, it makes Downloader.aspx the source of the the FLV player and the video is correclty presented and streamed into the player.
The problem I am having now is that any user interaction with the page (even typing an URL inside the same website domain on the browser address bar) becames hung until the video download ends.
I can measure this video download with HTTP Watch for example, and confirm that just after the video download into the player ends, the command issued by the user is immediately processed (or the browser goes to another page if the user typed a new address in the browser address bar).
I tought that it could be the limit of 2 connections per domain, but HTTP Watch only shows one active connection (the video download into the FLV player).
Even if it was this 2 connections limit, I think a nice solution would be to somewhat detect the user interaction with the page and abort that video download.
