aspnet_wp.exe (PID: xxxx) stopped unexpectedly.

[Matt Sollars]

Hi all.

I'm having a nasty problem. A client's website was originally written with
classic ASP. They requested a new portion of the site that was deemed a
perfect candidate for ASP.NET. So, .NET was installed on their web server
and one of the subdirectories in the web site was converted to a virtual
application to support the new pages that would be added. The rest of the
site was left untouched. New aspx files were added to this subdirectory and
compiled code was put in it's \bin directory. All worked well in testing,
even on their server.

Then, one day, a report was made that a user could not access one of the new
pages in the new virtual. A server error was being reported to the user. The
client's IT dept rebooted the web server to "fix" the problem and all worked
well again until the next night. Again, the same problem. Only this time,
the server was fine by the time I was told to investigate and no reboot was
performed.

I looked through the event logs for application errors and have found 3
different errors involving .NET.
1.) aspnet_wp.exe (PID: xxxx) stopped unexpectedly.
2.) aspnet_wp.exe (PID: 3148) was recycled because it was suspected to
be in a deadlocked state. It did not send any responses for pending requests
in the last 180 seconds. This timeout may be adjusted using the
<processModel responseDeadlockInterval> setting in machine.config.
3.) The system has called a custom component and that component has
failed and generated an exception. This indicates a problem with the custom
component. Notify the developer of this component that a failure has
occurred and provide them with the information below.
Component Prog ID: SC.Pool 9 4
Method Name: IDispenserDriver::DestroyResource
Process Name: aspnet_wp.exe
The serious nature of this error has caused the process to terminate.
Exception: C0000005
Address: 0x272116E4
Call Stack:
MSDART!MPInitializeCriticalSection + 0x11C
oledb32!CSCDispMan::GetDispenserManager(unsigned short *) + 0x3D
COMSVCS!ATL::CComPolyObject<class CStdTrustable>::QueryInterface(struct
_GUID const &,void * *) + 0x55

When I cross-reference the IIS logs with the timestamps reported in the
event logs for these errors, there doesn't appear to be any pattern. In 15
instances, only one of them seems to involve one of the new ASPX pages. All
other cases are in various directories, involving classic ASP pages. I don't
get it. Whenever the 3rd error occurs, it is always followed immediately by
the 1st error and whenever the 1st error is reported, no ASP.NET pages can
be displayed.

I cannot for the life of me get this to happen at will. They happen at
varying times of the day. I've even removed the new .NET pages and virtual
for the subdirectory, but it still happens.

Is there a way to prevent the process from stopping when things go wrong? Is
there a setting I'm missing? Why does it seem that these errors are
happening with pages that don't even use ASP.NET, yet the aspnet_wp.exe is
always the process generating the errors?

Please, help.

Hi,

If you are using any VB6 dlls from your pages check that Retained in
memory and Unattended execution options are checked. I got it once, this
behavior documented in MS.

Hello Matt,

Natty is right. "ASP.NET Worker Process (Aspnet_wp.exe) Is Recycled Unexpectedly" error is documented in one Microsoft
KB article. Please refer to [url]http://support.microsoft.com/?id=321792[/url] for details.

Hope that helps.
