IIS And Ajax UpdatePanel Results In Extreme Memory Usage?

Nov 26, 2010

I have a update panel combined with gridview with sorting and paging.

I go into task manager to monitor the memory usage of the worker process (w3wp)

What I do is just click on the sort buttons rapidly.

With each click the memory of the process increases with about 2 mb

So I go from 30 mb memory usage to about 90. Then it stops at remains there, no memory is freed up. I am not using caching or session/application state.

What can be causing this, is there a setting in IIS to reduce the mem usage?

I also used .net profiler to examine my app memory usage: 4 mb, so what is the other 86 used for??? Even though it repots 4mb, in task manager it says 90 mb, so this leads me to believe that the rest is namanaged memory which must be used by IIS in some way.

Configuration :: IIS Memory Usage Is Extreme - Is That Normal

Jan 6, 2011

I have an ASP.NET 3.5 app that collects data from a handful of external pages, parses the relevant bits and displays them in a table. Total data retrieved is 3-4MB and the resulting page is about 1MB. I am using synchronous WebRequest GetResponse for the retrieval, but the same problem existed using an asynchronous BeginGetResponse/EndGetResponse process.

There is no database access, no session storage, but an in-memory list of about 100 objects/1MB of data, plus a good amount of AJAX (AjaxControlToolkit). This issue appears on the very first run of the app, even if I have restarted IIS.

The issue:

When I run the app on my dev computer, the maximum commit charge is about 1.5GB. The biggest user, measured by Task Manager's VM Size, is WebDev.WebServer.exe (600MB). The app runs perfectly.

When I run it on my rent-a-server (IIS 7.5, 1GB RAM), the maximum commit charge is over 3.8GB. The biggest user is w3wp.exe at 2.7GB. IIS grinds to a halt and spits out a timed-out error page.

Given my limited server budget and the hope of having multiple simultaneous users, I'm kind of in a panic.

AJAX :: UpdatePanel Memory Leak IE8?

Nov 2, 2010

I created a site which fills an UpdatePanel with dynamically created buttons when clicking on an other button. Now every time I click the button the used memory increases. I already tried the workaround from http://www.crockford.com/javascript/memory/leak.html to remove old eventhandlers before updating the UpdatePanel. But the used memory still increase. Is there a problem with my code or is there an other workaround?

Here is the code of a sample aspx site which shows the problem: [Code]....

Browser IE8

OS WinXP SP2

AJAX :: UpdatePanel Memory Leaks In IE

Oct 11, 2010

After researching why a page I have using an UpdatePanel to perform a refresh every 15 seconds was using up piles and piles of memory over time, I discovered that this is a "well-known" issue with the UpdatePanel not cleaning up properly in IE (some issue with reference counting in COM interop or some such). UpdatePanel does not seem to have this issue in Firefox (haven't confirmed the issue in other browsers).If this is a "well-known" issue, two questions:Is there a "well-known" workaround to this? I know that a full-page refresh will cause the memory to be cleaned up, but some pages may be up for a long time and I don't want to interrupt any user interaction with the page that may be going on. I will if it is required, but it is a sloppy, sloppy UI kluge... you know, one of those "as a self-respecting coder I hang my head in shame at what I have wrought" kind of kluges.Is there any effort being made to fix this? I've looked about, however, most articles on this do not make mention of even MS acknowledging bug status for this while I've seen many telling me why this is an issue, and how it's a "design" thing. I hear IE9 is supposed to take care of this... I guess what you'd call a non-issue, but it will only be available to Windows 7 users.

What Is Normal Memory Usage Of A Mvc Website

Feb 16, 2011

I have really tried to Google it but only articles about how to troubleshoot memory issues come up. Before I start to troubleshoot, I would like to know if my web site's memory usage is really abnormal or not.

So it is an asp.net mvc 2 website that runs on IIS 7.5 in production. I guess normal memory usage depends upon traffic, so here are the numbers of an average day:

300 unique visitor
400 visits
3000 page views

I would be really happy to get some idea how much is the normal memory usage for this traffic. Also I would be curious to know how memory usage normally increases with traffic growth.

Memory Usage In IIS Is FAR Greater Than In DevEnv - Is This Normal

Jan 5, 2011

I have an ASP.NET app that scrapes data from a handful of external pages, parses the relevant bits and displays them in a table. Total data retrieved is 3-4MB and the resulting page is about 1MB.

Is this normal? If I bump the server RAM up to 4GB, will that be enough?

Response - Finding Memory Usage During Download?

Jan 22, 2010

On an ASP.net site at my place of work, the following chunk of code is responsible for handling file downloads (NOTE: Response.TransmitFile is not used here because the contents of the download are being streamed from a zip file):

[code]....

I've just read about the 'buffer' property of the Response object. If I set that to false, will that prevent the Response.BinaryWrite() calls from buffering the data in memory? In general, what is a good way to limit memory usage in this situation? Perhaps I should stream from the zip to a temporary file, then call Response.TransmitFile()?

EDIT: In addition to possible solutions, I'm very interested in explanations of the memory usage issue present in the code above. Why would this consume far more than 1MB, even though Response.Flush is called on every loop iteration? Is it just the unnecessary heap allocation that occurs on every loop iteration (and doesn't get GC'd right away), or is there something else at work?

Caching - Controlling Output Cache Memory Usage?

May 17, 2010

I would like to use output caching with WCF Data Services and although there's nothing specifically built in to support caching, there is an OnStartProcessingRequest method that allows me to hook in and set the cacheability of the request using normal ASP.NET mechanisms.

But I am worried about the worker process getting recycled due to excessive memory consumption if large responses are cached. Is there a way to specify an upper limit for the ASP.NET output cache so that if this limit is exceeded, items in the cache will be discarded?

I've seen the caching configuration settings but I get the impression from the documentation that this is for explicit caching via the Cache object since there is a separate outputCacheSettings which has no memory-related attributes.

Here's a code snippet from Scott Hanselman's post that shows how I'm setting the cacheability of the request.

C# - Page Explodes Memory Usage To 80MB And Then Dies?

Feb 25, 2011

I'm using asp.net and chrome and the page becomes unresponsive after a while. When I look at the chrome debug, I see that memory usage increases to about 80MB and chrome popups a request to kill the page. The error counter spins and generates about 30,000 errors when the popup comes. What triggers the error is the call of an updatepanel. The error as displayed in chrome is "Failed to load resource".

The update panel: the user clicks on a button and the panel is refreshed. There's only one update panel on the page.

This is what I have:

function HistoryUIActions() {
$('.SelectDay, .SelectDay1Digit').click(function () { GetNewDate(this); });
};
function GetNewDate(thedateitem) {
var TheDay = $.trim($(thedateitem).html());
TheYear = 2011;
ThisMonth = 2;
DateString = ThisMonth + '/' + TheDay + '/' + TheYear;
__doPostBack('<%= TheUpdatePanel.ClientID %>', DateString);
};
function EndRequestHandler(sender, args) {
HistoryUIActions();
};

The errors compound on every postback: 1,4, 11, 26, 57, 120, 247.... eventually chrome kills the page. When I put a breakpoint in the function, it stops the code just after I press the button; then after it hits the __doPostBack line, it starts the GetNewDate function again several times by going back to the line of the click event, apparently executing it the number of times shown above.

AJAX :: Timer Results In Updatepanel Gives Full Postback

This gives a quite strange result: Every 5s my whole page gives a full postback. When I comment in (activate) the asyncpostbacktrigger, the updatepanel does not give a full postback. In the PlayerItems_ItemDataBound I have the following code (which, I do think, do not matter):

When I create a NEW updatepanel, ItemsUpdatePanel1, it does not fire a full postback without the timer. I can even start copying items from ItemsUpdatePanel to ItemsUpdatePanel1, and suddenly the full postbacks happen. I tried 2 seperate times, and they started happening at different times. I simply want the UpdatePanel NOT to give a full postback, even without a timer.

Environment.WorkingSet Incorrectly Reports Memory Usage For A Website That Runs On Windows 2003 Server

Jul 31, 2010

Environment.WorkingSet incorrectly reports the memory usage for a web site that runs on Windows 2003 Server.(OS Vers: Microsoft Windows NT 5.2.3790 Service Pack 2, .NET Vers: 2.0.50727.3607)

It reports memory as Working Set(Physical Mem.): 1952 MB (2047468061).

Same web site runs locally on Windows Vista with a Working Set(Physical Mem.): 49 MB (51924992).

I have limited access to the server and support is so limited.

so i have computed the total memory by traversing with VirtualQuery.

Total of pages with state: MEM_FREE is 1300 MB.

(I guess server have 4 GBs of RAM and PAE is not enabled, max user mode virtual address is 0x7fff0000.)

So, i know working set is not only about virtual memory. But, is it normal to have such a high working set while its very low on another machine?

Getting Mixed Results With Page Validation And Modal Popup Usage On A Page?

Mar 9, 2010

I have a page that works great until now that they wanted to add a ModalPopup based on a field value. Before the addition of this modal popup, i had a button event that would do the inserting of the data, it caused the page to validate and as long as the page passed then it would insert and move on to the next page. Now i have a ModalPopup displaying IF a certain field is empty. If they answer Yes to the modalpopup question, it takes them back to the page and sets the focus on that field. Works fine, but if they select No then i need the page to validate and insert the record and move on.I have a customvalidator for the field i need to check. I then have my insert on the main button that causes the validation. The "Yes" and "No" buttons within the modalpopup have the following setup.
[Code]....

My Main submit button has the following:
[Code]....

If i select NO it just goes back to the page and doesnt move forward. If i select YES and enter something the page pops up the modal again and again because i've clicked in the field and keeps asking even though there is now a value in the field. But since there is a value, i can continue on to the next page.

AJAX :: Reg Usage Of Ajax Tabbed Control?

Mar 5, 2011

my requirement is like, I had a tab container in a webform, where I had two tab panels, one is for user registration, and another is for getting confirmation from the user, Now I had created the user registraton form, and need to create the user confirmation form, on confirming the user will click submit and an insert stored procedure will gets fired. Now, my main issue is like, which would be the best way, I would like to display the user entered information in the confirmation tab, like, generally, we view some records of data in a details view, using alternate row styles, in that way, I am planning, so which would be the best way, should I create a table and style it or can i use details view or grid view or form view or anything else which u can suggest.

Thing is that the user should view the page in a rich format, well structured and also how to allow the user to edit if required, and which would be the best idea, should I redirect the user back to the first panel or can we edit there itself, on the top right corner, the user should find the edit option, so how should I place it over there. Seems like a big requirement, bt expecting a big hand from you ppl to newbie like me in this technology..
