Thread.Abort cause IIS w3wp.exe crash RRS feed

  • Question

  • Hi,

    current we encounter a strange crash in IIS w3wp.exe process. in application.PreRequestHandlerExecute handle, if there is a ThreadAbort exception, the whole w3wp.exe will crash.

    my environment: windows 2012 R2 + .Net v4.0.30319

    i searched internet. find there are many topic to discuss this problem: that ThreadAbort exception cause w3wp.exe to crash. and Microsoft provide the update.  e.g: https://stackoverflow.com/questions/32335020/thread-abort-in-asp-net-app-causes-w3wp-exe-to-crash

    but that update didn't apply to Windows 2012.  

    i can avoid this by remove finally hanlder (try.catch.finally) in application.PreRequestHandlerExecute handle. but i don't know why. normally ThreadAbort exception will not crash a process. Does anyone know some information about it? Thank you very much.
