I need a routing that periodically checks for the existance of an ex.err. If found, it will email the file to me. Rob mentioned he had one like this once but I can't find one in the archives. Does anyone or Rob have one they can share? I know how to find ex.err and email it, but I don't know how to start a background task to look for one every few minutes/hours.

Thanks for any help.
