Hi Michal, Thanks for the quick response, I have some questions
A) This is consistently from job_unpost rather than job_post, is a separate fix required in the job_unpost code? B) We download the release from att and use those instead, has this been fixed in the latest att release?

Yes, most probably you see this bug. It's fixed in rhel5 and for rhel4 the bug (#455316 bug is private) is approved so it'll be fixed in rhel 4.9 Michal -------------------------------------------------------------------------- NOTICE: If received in error, please destroy, and notify sender.
