-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 This seems a synchronization problem. A scenario description could clear things up so we can help:
Program W (The workflow) copies file F to directory B Program D (the dog) polls directory B to find is there's any new file F In this scenario, program D does not know whether F has been fully copied, but W does. Solution: Create a custom lock mechanism. Program W writes a file D/F.lock to indicate file F is not complete, it's removed when F is fully copied. I program W crashes in mid-copy both F and F.lock are kept so program D does not bother to process F. Recovery from the crash in W would another issue to tackle down.
