Can you post the code of this script? Are you trapping all exceptions in that script and making sure you only return errors when there really is an error?

You are calling the php command from a shell script, so there's multiple places things could go wrong. Why not just pipe directly to the php script (which wasn't included unless I'm totally blind and dumb tonight... :-) instead?
It honestly sounds like a timing issue, maybe just putting a sleep into your shell script at the end would be good? Or maybe run with the -vx switches so you log all the commands and their results?
