Troubleshoot intermittent crashes in web applications (ASP.NET)

Reports have been received that the web application is shrinking twice in three weeks. Some reasons need to be analyzed. works fine after reboot. I am not an expert in this area.

It is hosted on IIS and Windows 2003.

There is nothing interesting in Event Viewer and the IIS logs only show many successful operations GET

. There is nothing interesting about the SQL logs on the remote SQL server to which it connects.

I'm not sure how to decrypt the IIS log. It just looks like a bunch of successful messages GET

with no errors.

I don't think I can really get too many root cause analysis results to figure out the root cause of the problem?

Depending on your traffic, twice every three weeks doesn't sound like much. The root cause might be related to the fix, if you were able to recover it by restarting IIS, it might be a memory leak. If you had to restart the server, this could be a deeper problem.
