I have a memory leak somewhere that I cant find. Every few days my server will crash, and just before that I log a ton of SQL errors stating that it is "out of memory".
I cant find it anywhere, all of my connections are being disposed like so:
[Code]....
Then I call the connection from my pages like so:[Code]....
That is all pretty straight forward. The connection is disposed because it is implementing the USING clause. I am opening the connection in my connection manager class, and not where it is being utilized?Or, could the problem be in the below method I am using to populate a SqlDataReader:[Code]....
Now, at first it appears as though this could be the problem because the Connection isn't part of a USING clause, however doesn't the 'Data.CommandBehavior.CloseConnection' pretty much do the same thing. This makes sure that the connection is closed when the reader is closed, right? Here is how I call that above reader from my login page code behind:[Code]....
So the DataReader will get closed even without the .Close() because it is in the USING, and the connection should get closed because I specified it in the ExecuteReader paramters right?
A customer reported that our asmx web service is continually increasing in memory (mem usage as well as private bytes). We are able to reproduce the problem in our lab with Windows 2003 Server SP2 (fully patched) on some of the machines. The customer is using Windows 2008.
We created a Hello World web service targeting the 2.0 framework built under VS2005 SP1 and a test client that continues to call it. The memory increases steadily - approximately 40K per client request. If the test app is paused, the memory remains the same. When it is closed, the memory drops. Explicit calling of GC.Collect does not drop the memory.
We have run the memory profiler on the service and the leak is all native memory. We have uninstalled/re-installed the Framework on one of the machines but no difference. To our knowledge all of the security and IIS settings are not modified. We have compared app pool, default web site and virtual directory properties to machines that have no problem and they are identical.
I am building an asp.net application, using II6 on windows server 2003 (vps hosting).
I am confronted with an error I didn't receive on my development machine (windows 7, iis 7.5, 64 bit).
When my wcf service tries launching my query running against a local sql server this is the error I receive:
Memory gates checking failed because the free memory (43732992 bytes) is less than 5% of total memory. As a result, the service will not be available for incoming requests. To resolve this, either reduce the load on the machine or adjust the value of minFreeMemoryPercentageToActivateService on the serviceHostingEnvironment config element.
I have both VS 2005 and 2008 installed on my machine. 2005 is fine. For 2008, literally any asp.net project I try to create gets this eror. I try stepping into the code, and the error occurs apparently before anything that I can trap is loaded. There is no information written to the event log. I have tried this with a "Hello World" webpage with nothing else going on. Seems unique to my Windows Server 2003 machine.
View 3 RepliesI am getting a weird error in asp.net while using leadtools imaging api. Here's the stack trace.

I am maintaining C# .NET code written by somebody else, I get following exception few times,Attempted to read or write protected memory. This is often an indication that other memory is corruptThe code structure where I get the above exception is somethign like this,- it is using ref variables in following sequence,Variable-1 and variable-2 are local variables in App1, - App1: func1() which passes these variables reference to func2(), - App1: func2() passes same variables reference via .net remoting to another application (App2).-App2: does the same passes same received reference to another call 2 times.- The execption is occured while returning from App2.
(App1:func1(ref Var1, ref Var2) --> App1:func2(ref Var1, ref Var2) <---App1 .net remoting to App2--> App2:func3(ref Var1, ref Var2)--> App2:func4(ref Var1, ref Var2)-->variables getting updated and function returned to original caller)
My doubts are ,1. Is passing reference variables in such chain is correct? will it cause such exeption? Does .net support ref variable call directly?
I am unable to connect to my local instance of SQL Server 2008 Express using SQL Server Management Studio.I believe the problem is related to a change I made to the connection protocols. Before the error occurred, I had Shared Memory enabled and Named Pipes and TCP/IP disabled. I then enabled both Named Pipes and TCP/IP, and this is when I started experiencing the problem.
I have now set Named Pipes and TCP/IP back to disabled. When I try to connect to the server with SSMS (with either my SQL server sysadmin login or with windows authentication), I get the following error message:
"A connection was successfully established with the server, but then an error occurred during the login process. (provider: Named Pipes Provider, error: 0 - No process is on the other end of the pipe.) (Microsoft SQL Server, Error: 233)"
My first question here is: why is it returning a Named Pipes error? Why isn't it using Shared Memory? It seems like it is not listening on Shared Memory for some reason?When I set Named Pipes to enabled and try to connect, I get the same error message.My windows account is does not have administrator priviliges on my computer.

I've got a lightbox with a small form (2 fields) in it, inside an UpdatePanel, and I want to close this lightbox (must be done via javascript) when the 'Save' button is pressed.
However, there is a need to have a server-side CustomValidator on the page, and I only want to close the lightbox if this returns as valid.
Does anyone know a way to trigger javascript (or jQuery) code from a server-side validator?
I have a textbox that I need to enter a path directory into, for storage in my database. For example, I need to enter "D:DocumentsFilesPhotos"
Is there a way to browse the server directory in a similar fashion to the FileUpload control? I do not need to upload a file, I just need exactly the same functionality as the textbox part of the FileUpload control! (i.e. When you click in the textbox, a browser opens, you select the folder, the path is filled into the textbox for you) P.S. I searched a few existing posts already on this, but several were dead ends, hence another post!
I'm not sure why but on random occassions after I have added an update to my site via ftp and then try to access the site through the browser I get an "out of memory" exception. But there are no infinite loops or problems like that. Then after some time it will then work (I assume the web hosts restart IIS or something) and all is fine again. Server Error in '/' Application. Exception of type 'System.OutOfMemoryException' was thrown. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

How do I create a text file and write the contents of a string to it? I plan to reference to the text file later. It could be on the server (root folder) or anywhere where I can reference it. Below is the string contents

{
if (result.Contains(s))
result = result.Replace(s, stringToReplace);
I have a memory issue on my websites and am trying to get to the bottom of it. I have downloaded the 14 day trial of ANTS Memory Profiler and have been playing with it to get a grip of what it's telling me. In the memory options on the timeline, I can see Bytes in All Heaps and Private Bytes etc but I am not sure which ones I should be focusing on to see where the memory spikes and doesn't go back down.I am profiling a ASP.NET website using ASP.NET 2.0.

View 4 RepliesI used to work in the IT field, but because of an accident and meds I have lost a bunch of my memory. So, I'm in need of relational database help..I've got a web site I want to put up that will sell books. I'll be using SQL server 2008. I'll be using Pay Pal's Cart, etc, so I just have to put up some buttons on the web site, but I need to track, display, etc, the books and properties about the books such as Authors, Paper back or hard cover, first edition, or something else, etc,..I have a table for books obviously, but I'm wondering if I should break out the Authors out of that table? I mean I don't see why except that if I end up with some books that have the same author then there names will be stored more than once, but I will be doing a lot more queries than inserts. I've got Customers, Book Types which is if the book is a hard cover, softcover, first edition, etc,. I will relate the Books to the Book Types of course, but again, should I have an authors table? Hope this makes sense.. I am using Visual Studio 2008 Pro, and want to do my relations there, so I thought I'd do so in the IDE if possible? I can't remember, but I thought it was possible?
View 6 RepliesI'm calling a static Page method via javascript that takes between 5s and 10 min. I'd like to give my user the choice to either continue waiting for the request to complete or not, and use window.setTimeout() to check back every 30s.
I've tried both location.href = '/newpage.aspx' or firing a button's click handler (which does similar redirect) to redirect the user prior to completion of the page method, to no avail. I can immediately send user to a simple html page, but a redirect to any aspx page involving server-side appears to block. When the page method finally completes, the redirect does succeed.
Is this:
a browser issue? If all modern browsers support at least 2 concurrent requests per domain, why wouldn't this work?
a framework limitation? a desirable design pattern or even possible? I've checked, and after redirecting to an HTML page, the original request continues processing (db updates, no problem).
Consider this code:
Partial Public Class MyAspNETClass
Inherits System.Web.UI.Page
Protected Shared MyVariable As String
Is Myvariable a variable used local for each instance of the page ? Or that variable is "shared" for all users accessing my page? Is MyVariable saved in server memory, or is it saved on the viewstate of aspx page?
I have developed my web app in 3.5 framework and deployed at high config server(15 gb ram). In my app there are some rdlc reports which always throws out of memory exception. each report has around 15-20 pages. rest of pages are working fine. there are 700-800 users hitting this site concurrently. i m checking my server utilization and its never gone beyond 2 gb. wot i need to do so that my app can utilize full memory.

View 4 RepliesEnvironment.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?
I have a .Net Webservice(2.0 framework) and I am trying to call this service from SQL
server 2005 using CLR.
I have created assamblies on server and trying to call the we service through CLR, but I'm getting below error:
"Exception:
Server was unable to process request. ---> Invalid URI: The URI is empty."
I m having a database problem that I couldnt identify. The IIS loses connection to database once in 3 weeks. Once you restart the IIS everything is normal. Looks like IIS is fine because i can go to static pages. When I go to a page that requires database connection I get this error:
A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - Either the application has not called WSAStartup, or WSAStartup failed.
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
Is this a connection string problem?. because without changing anything if I restart the webserver all is fine. Is this a problem with application state?
