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
.Net Framework 3.5 SP1

I'm using the ToolkitScriptManager on a page so that I can use the update panel. Everytime I refresh the page the mem usage in task manager jumps up 3-4megs. I'm using IE7 and have removed all inline JS and JS files to no avail.

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?

On http://msdn.microsoft.com/en-us/library/w070t6ka(v=VS.100).aspx there is an example on how to do impersonation with .net 4.0. We have used this example in a class that inherits IDisposable for ease of use. However, when we use this class in a asp.net web application, we notice a slight but steady increase of Pool Paged Bytes in performance monitor. After a week, the application crashes.
I've tried different implementations of the impersonation-class, using http://msdn.microsoft.com/en-us/library/w070t6ka(v=VS.90).aspx and http://support.microsoft.com/kb/306158 as reference, but they all show the same leak.
Where does this leak come from? Is there a problem with the windows api? We are running Windows 2008 R2.
This is our current version of the impersonation class:
public class Impersonator : IDisposable
{
public Impersonator(string username, string domain, string password)
{
if (!ImpersonateValidUser(username, domain, password))[code]....
And this is the performance monitor graph of two webservers using different versions of the class:
When we disable the class, and use global impersonation via web.config, those lines are completely flat.
Update,I have made a test-application that successfully reproduce the problem. It can be downloaded here:
http://rapidshare.com/files/447325211/ImpersonationTest.zip
The result over 18 hours looks like this:

I'm writing an MVC app and want to have a central DataBase factory class to provide all my DB connections, something like this:-
[Code]....obviously I'll have to instanciate this every time I need to use it, so I was thinking of making it a static class:-
[Code].... so that instead of my controller code saying
[Code].... I can just say
but would this cause a memory leak? I'm sure I remember reading somewhere that if a static class creates objects that persist beyond it's methods and return those (esp things like DB connection objects) these won't get garbaged collected when the calling method is disposed of as they were created/referenced outside the scope of that calling (controller action) method and so will hang around in memory?
var tableObject = DatabaseFactory.GetDatabaseTable();
List<DbRecord> records = tableObject.Table.ToList();

I have an .Net Framework #4.0 application that makes a large number of web requests using the WebRequest/WebResponse classes , as i see it has memory leak (or maybe i am doing something wrong)I Wrote some small simple application that demonstrates this:
class Program
{
public static void Main(string[] args)[code]...
The only one solution i came up with is use GC.Collect() (unmarked in example) , All the object are disposed , all streams are closed , am I missing something ?I found something but i don't understand the reason , if i minimize Console the memory usage decreases and looks O.K , what can be the reason for that is there a problem with Conosole or WinForm .

I've created a small class library to asynchronously call a WebService(Fire and Forget. I don't need the result).In a Windows Form application, the XXXAsync() method works fine. But, in a Web Application, the process is locked until the XXXCompleted event is fire.My problem is: I tried to create a Delegate and use the Begin/EndInvoke to call the XXXAsync() method. It worked fine, but, the w3wp process seems to be consuming a huge amount of memory. I'm calling the EndInvoke method properly. Invoking the GC.Collect did not free any memory

Any tips How to figure out where is memory leak in my Facebook app, its ASPX using Facebook toolkit DLL and I am afraid the bug may be in that CS library.
The problem is that after one week uptime, server is running out of memory and needs to be rebooted, there are quite many users and I cannot run debugger on this "production server", so I would need to simulate somehow use on my local PC.

I am facing problem memory leak when I bind GridView to my dataset. The dataset will be retrieve when page first loaded (Not postback) and store into session. ANy postback will reuse the dataset from session.
The problem now is, whenever any postback, the memory leak is keep increasing and till 1GB. I read some articles and mentioned it is ASP.NET databind issue. Is it true? Any workaround?

I am using DevExpress Gridview basically, and hit out of memory exception whenever I keep refresh page that contains huge data. I reported to DevExpress team and they claimed it is ASP.NET gridview issue.
Therefore, I create a simple project, a girdview to sqlDataSource. Run the page and press F5 to refresh. I use ANTS profiler to check if any object instance is keep increasing but never been disposed. I found that, memory does happen in this simple project, as what DevExpress team claimed.[Code]....

I have an application which was recently ported from Classic ASP to .NET 3.5. I'm pulling some data from a stored procedure and once retrieved, I'm doing using the Select method on the DataTable in a loop so I don't have to keep going back to the database.It appears that there's something wrong here as I can refresh the page repeatedly and see the memory usage increase by a few megabytes, up to the point where we get an error. If we recycle the app pool in IIS, it starts working again, for a little while.
Is there a memory leak in this method? I did some research on the subject and Microsoft said there was an issue like that in .NET 1.0 and 1.1, but I'm using a higher version.Or, is this something else, such as not managing resources correctly? Here's a snipped of my code:
[Code]....
Initially, this app was using XML instead of a datatable and using XPATH to query the data, but it was too slow. I thought using a dataset with DataTable selects was a better option, but now we found this issue. I was thinking since the loop executes several hundred times that getting all the data and filtering through it on the client was a better choice instead of calling several web methods to get the subsets of data.

It happens frequently when I try to copy & paste code inside VS 2010 with following message:
insufficient available memory to meet the expected demands of an operation at this time, possibly due to virtual address space fragmentation. Please try later.
and I check the memory usage with taskmanager on my computer. It is fine.
In order fix it, I need to close VS 2010 and restart again.

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.

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.

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.

i am using a TabContainer and at each TabPanel i have embed an UpdatePanel in order to update each tab alone.
this is my code:
[Code]....
the problem is that it makes several seconds to update each tab (the same time for every tab) and i asume that this is happening because it updates all the TabContainer and not the selected Tab.

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 have two updatepanels on my site (upanProfileSearch and upanMemberList). When I hit the button in the upanProfileSearch it should bind the Data Items in the gridview in upanMemberList and here make a RowFilter on the text in upanProfileSearch. When I make a run to curser, I can see, it happens. It makes a RowFilter. but it doesn't update the gridview. Can anyone tell me why it doesn't update? I have UpdateMode="Always" and RenderMode="inline" on both UpdatePanels.

I have a dropdownlist, that causes a postback. On the SelectedIndexChanged event, is it possible to force a placeholder that is within a different UpdatePanel to change it's visibility?
For example, when the SelectedItem.Value of DropDownList1 is "1" then show Placeholder1, otherwise hide it.
What I am most interested in is how to configure the UpdatePanels to allow this.

I have a web user control with one updatepanel (pnlUpdate_2), some controls and one apply button. I display the web user control as a modalpopup in my default page. In my default page i have an updatepanel (pnlUpdate_1) with a gridview and I modify that gridview with the apply button of the web user control. The web user control is for made a custom search of the gridview data. I have a problem with both updatepanels. If I set the updatemode as always in one of them (pnlUpdate_1) and the other as conditional (pnlUpdate_2), the pnlUpdate_1 make a postback in the pnlUpdate_2; I'm not an expert on this but I think that's why the pnlUpdate_2 disappear and reappear after postback of some controls in that updatepanel (not the apply button, it close the modal after postback). I try all the combinations and the problem persists. So I put both updatepanels as conditional and in some way it works; now the problem is that when I click the apply button in pnlUpdate_2 to modify the gridview in pnlUpdate_1 the pnlUpdate_1 not made the postback I get the pnlUpdate_2 postback when I use some control inside the pnlUpdate_1.
How can I postback the pnlUpdate1 from pnlUpdate_2 with the apply button?
