Status 24's can be straight forward or pretty tricky. I would start by looking at the detailed status of the failed job to see if you can determine which daemon/service generated the status 24 error.
How far along does the job get before it fails? Is communication established with the client when it fails? Or does it fail trying to communicate with the client?
If you can tell check the log for the daemon/service for the details of the status 24 error and post those errors here.
