  IIS 6.0: .net framework errors out randomly cause all aspx pages to stop working.. please help !! Reply Contact Hello Everyone  I have my site running on IIS 6.0. The site contains a mixture of asp and aspx pages. The aspx pages are all written in vb.net and use .net  v1.1  I randonly get "Service Unavailable Error" and immediately all the aspx pages stop working. The only way to get it back up is by restarting IIS. I am never able to reproduce the error and the error does not happen on the same pages. The errors occur all over the site. I have no idea how to approach this issue. All my error notification processes fail since they use .net and since the framework bombs out on me they fail too. Mind you when the aspx pages stop working, all the asp pages are still up and functioning.  In short, the errors happen randomly, I never get notified, the event log and the IIS logs dont have errors logged to help me point in the right direction. I hope someone can help me out with this issue.  Thank you

  Re: IIS 6.0: .net framework errors out randomly cause all aspx pages to stop working.. please help !! Reply Contact This is just a few ideas when I'm troubleshooting issues like this.  1) Are you doing any type of logging to a text or log file on disk?  Maybe there was contention on the file causing an issue. 2) Are there any errors in the event log?  Make sure you turn on auditing to see if any errors are logged.  .NET 1.1 does not log as well as 2.0. 3) IIS has a good diagnostics.  http://www.microsoft.com/downloads/details.aspx?familyid=9BFA49BC-376B-4A54-95AA-73C9156706E7&displaylang=en 4) Also try IISState utility by Microsoft. 5) Investigate the IISLogs to see what webpages were called just before the issue occurred.  You can use Log parser to extract the logs for specific times.  This can help find a pattern. 6) Are you running multiple applications or websites in the same application pool?  If so, maybe try isolating applications into different pools. Hope that helps provide some direction. Steve Schofield Windows Server MVP - IIS http://weblogs.asp.net/steveschofield http://www.IISLogs.com Log archival solution Install, Configure, Forget

  Re: IIS 6.0: .net framework errors out randomly cause all aspx pages to stop working.. please help !! Reply Contact Hello Steve Thank you very much for your response. I will definetly start looking in the direction pointed by you. It seems like it might help me figure out this issue.  I do have only one application pool since its just one website.  The logging is the default logging set up by the sys admins, the one that is provided by IIS. The event log does not show errors every single time. Sometimes, they tend to show some weird errors kinda pointing in the direction of a memory leak, but does not really tell me if thats the case, where did that happen.  I will post as soon as I make some progress. Thank you again
