The process running the web automation is crashing intermittently. We cannot always reproduce. My question is if you know about the error and if it is anything in the override of OnException that is wrong that could cause this. Basically we do not want the process to crash but only log the errors.
Thanks
Crash error in dmp file:
System.IO.IOException: 'The handle is invalid.
This exception was originally thrown at this call stack:
[External Code]

System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, object) in executioncontext.cs
System.Threading.ThreadHelper.ThreadStart() in thread.cs
OnException override code:
protected override void OnException(Exception ex, bool exiting)
{
if (WebResultObject != null)
{
WebResultObject.AddOutput(ex.ToString() + "|Exiting:" + exiting, true);
}
if (CurrentContext != null)
{
CurrentContext.Abort(ex);
}
base.OnException(ex, exiting);
}

Hi,
If you do not call base.OnException(ex, exiting) in your OnException, the process should not crash. base.OnException would automatically rethrow the exception thus causing the process to crash.
Thanks!
