We’ve been receiving an ASP.NET Error on our server for almost a year. As we’ve seen an increase in traffic on the server over the last few months, the errors have increased in frequency as well. We’ve also begun experiencing issues on the
sites themselves at the same time the errors are occurring. (ex. sites freezing up ) Stopping and restarting IIS on the app pools will solve the issue. This server is running MS Windows Server 2003 R2, MS .NET Framework 3.5 SP1.
To troubleshoot this issue we have placed sites with heavy traffic in their own app pools, checked the windows updates to see if an update was installed around the time the error began, reviewed all of the sites searching for a common denominator. The error
seems completely random over many different sites with no visible common factor.
How do I figure out what the following error means?
Event Source:ASP.NET 2.0.50727.0
An unhandled exception occurred and the process was terminated.
Application ID: /LM/W3SVC/1/ROOT/site
Process ID: 7992
Message: Thread is running or terminated; it cannot restart.
