Web Forms :: Memory Leak When I Bind GridView To My Dataset?

Oct 29, 2010

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?

Forms Data Controls :: Memory Leak - Gridview

Jan 13, 2011

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]....

DataSource Controls :: Memory Leak - Server Will Crash - Log A Ton Of SQL Errors Stating That It Is "out Of Memory"

Jul 27, 2010

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:

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?

C# - Impersonation Memory Leak

Feb 9, 2011

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:


The result over 18 hours looks like this:

MVC :: Memory Leak In Database Factory

Jun 14, 2010

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();

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]....

C# - WebRequest/WebResponse Memory Leak?

Dec 7, 2010

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 .

.net - Possible Memory Leak In Asynchronous .NET Call To A WebService?

Sep 16, 2010

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

DataSource Controls :: Possible Memory Leak In DataTable.Select Method?

Jun 18, 2010

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:


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.

Forms Data Controls :: Bind Data From DataSet (DataTable) To A Selectrow DropDownList In GridView?

Nov 19, 2010

I have a Gridview and two link button in that GridView , one link button click is to add edit row ( Edit ), one link button click is to select row ( Select ). I have a dropdownlist inside row which selected when i click link button Select in the gridview edit template, as of my business logic i need to show the dropdownlist only when the user clicks Edit button and when the user clicks Select button . That mean when the user clicks Select button then they clicks Edit button on the gridvview i should allow him to edit the dropdownlist (showing the value to the user through a label).


[Code].... C#

When I click Select link button , then I click Edit link button . They have errors : Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index" I don't know what error?. How to fix it

DataSource Controls :: Datatable/Dataset Total Memory?

Mar 16, 2011

make a query which will give me 200,000 results and bind it to the datatable but the error will pop out saying out of memory or request timed out.Can datatable/dataset handle these records or is my current server's hardware needs a little upgrade?Actually we are gettings millions of data and i dont have any idea how to solve this one? Have you worked on this kind of data? Do you have any idea on how to send my command from server A to server B while server A also processing request and will not wait for server B's result and server B will just update the records in my database, i think this can solve my problem if doing it in parallel.
