>Yes I believe that is the process ID - and you won't see it on the task manager because the process has already terminated due to the error....or at least I think that would be the case. ...perhaps you might still see it if the user hasn't acknowledged the error yet.

Thanks, there is no interaction with a user as this is a robot. So, we have no error log as the error is not trapping anything. We cannot simulate that on our test environment. This happens from time to time on a production server. I just became aware of that and was trying to gather some information on it.
