title: .Net Runtime 2.0 Error - EventId 5000
body: <p>I have a recurring problem with a site that keeps giving me .Net Runtime 2.0 Errors in the Application Event Log, with Event ID 5000.  The event details are:</p>
  
  <p>EventType clr20r3, P1 w3wp.exe, P2 6.0.3790.3959, P3 45d691cc, P4 app_web_n93dosww, P5 0.0.0.0, P6 4b322f31, P7 37, P8 195, P9 pageerrorexception, P10 NIL.</p>
  
  <p>Looking on the web for this type of error, I found this article <a href="http://support.microsoft.com/?id=911816" rel="nofollow noreferrer">Unhandled exceptions cause ASP.NET-based applications to unexpectedly quit in the .NET Framework 2.0</a></p>
  
  <p>to give me more details of the exception, but for these errors, nothing extra is logged (the module in that article is working - if I add in the code they suggest to reproduce the error, the extra detail is logged).</p>
  
  <p>My question is really, if it is an unhandled exception that is causing these crashes, what situations could be causing it be unhandled?  The exception type in the message, pageerrorexception, is a custom exception that is thrown in a few different places on a few different pages, so it should be easy enough to track down.  But I can't see any situation where it would be unhandled and cause a crash.</p>
  
  <p>Any suggestions would be greatly appreciated.  Thanks in advance!</p>
