How can I get the dump for troubleshooting my asp.net code?

[Wei Lu]

I publish a web project on my IIS Server. But sometime, it hangs. Everytime,
I recycled the Application Pool, it works again. And I could not find
anything in the eventlog. Could anyone tell me how to get the memory dump
for troubleshooting? Or any solutions?

There was no way for you to know it (except maybe by browsing through some
of the previous questions in this newsgroup before posting yours - always a
recommended practice) , but this is a classic (COM-based) asp newsgroup.
ASP.Net bears very little resemblance to classic ASP so, while you may be
lucky enough to find a dotnet-knowledgeable person here who can answer your
question, you can eliminate the luck factor by posting your question to a
group where those dotnet-knowledgeable people hang out. I suggest
microsoft.public.dotnet.framework.aspnet or the forums at www.asp.net.

Hi Wei,

My name is Allen Chen. It's my pleasure to work with you on this issue.

To troubleshoot IIS hang issue you can use Debug Diagnostics 1.1:

http://www.iis.net/downloads/default.aspx?tabid=34&g=6&i=1286

From its documentation you can learn how to Troubleshooting Hangs with
DebugDiag. You can set up a Hang Rule to monitor the w3wp process and
create a hang dump by reproducing the hang.

After you get the dump you can use the analysis tool of the DebugDiag to
analyse the dump. Please try following steps to do so:

1. Run DebugDiag. Click "Advanced Analysis" tab.
2. Click "Add Data Files" at the bottom to add the dump file.
3. Double click "Crash/Hang Analyzers" category.
4. View the analysis report. It can give you clues as to what might be the
cause of the hang.

Regards,
Allen Chen

Doubtlesssly sincere, Steven, but the wrong answer for this NG.

The answer should be:

This is a classic asp group.

Dotnet questions should be asked in [par example]
<microsoft.public.dotnet.framework.aspnet>

Hi Evertjan,

Thanks for your remind

Yes, I should have mentioned that first and
microsoft.public.dotnet.framework.aspnet is the best one for ASP.NET
managed web application issues.
