How to debug iis "Service Unavailable" and (possibly) related w3wp.exe error in event viewer


suddently my website (asp.net-mvc iis) is down with error "Service unavailable". when i go to check the event viewer i see this error:

Source: VsJitDebugger

Error: An unhandled exception ('') occurred in w3wp.exe [5208]. Just-In-Time debugging this exception failed with the following error: Debugger could not be started because no user is logged on.

i tried starting and stopping the service but didn't seem to fix anything.

Is this an application bug or an enviroment issue? Can someone point me in the right direction on how to debug this. Site works fine locally (of course)


Solution

  • found stackoverflow exception in my app which caused this issue. had to push out a new version and reboot the box and issue fixed.
