Capturing System.AccessViolationException

I have a Windows service that crashes in an unhandled way with the exception System.AccessViolationException. I does happen in one of 1000 cases when trying to load a user profile (during impersonation). While I am interested in finding the solution more importantly is that I cannot capture this unhandled error - and terminate my service in a good way.

During start I have added this exeception handler:

AddHandler AppDomain.CurrentDomain.UnhandledException, AddressOf UnhandledException

If I hard code throw System.AccessViolationException as the same place in the code it is captured by my handler. But in the 1 out of 1000 calls the process is terminated and I can only see information about this in the event viewer.

Any ideas how to capture this?

Have you tried this?

Try
    'your code
Catch ex As AccessViolationException
    'write your ex.ToString() on a file or whatever
End Try
