Out .Net application is crashing occasionally after running for several hours with the error below in the EventLog.
We have attached a handler for the UnhandledException in the AppDomain which simply logs errors to the EventLog, but it looks the the CLR is going down in flames. Any ideas on how to track this down? Note that this is occuring on our production machine, so we don't have access to the debugger there

Hi Philip

How about logging the StackTrace from the exception that is thrown? It may
give you some idea where in the program things go wrong.

Hi,

I agree with Chris that you should catch the exception and dump the call
stack so that we can check where the problem is originated from.

In addition, is it possible for your to post a simple project which is able
to reproduce the problem? That will be most helpful for us to pinpoint the
problem and resolution.

Have a nice day!
