Just so you know, in case I wasn't clear enough, this happens after the LAST job runs. Interestingly enough, the previous jobs (since I'm running concurrently) all succeed no problem, and all have "Device busy" for the TapeAlert command. I don't even notice the problem until the next backup (catalog backup a few hours later), so it apparently crashes after sending out the success e-mail and closing out the running set of jobs. Don't know what-all happens in the code at that point, but I don't find out the -sd has crashed until the next backup fails. - -- ---- _ _ _ _ ___ _ _ _ |Y#| | | |\/| | \ |\ | | |Ryan Novosielski - Systems Programmer II |$&| |__| | | |__/ | \| _| |[EMAIL PROTECTED] - 973/972.0922 (2-0922) \__/ Univ. of Med. and Dent.|IST/AST - NJMS Medical Science Bldg - C630 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGriWKmb+gadEcsb4RAoZ8AJoDFK99GqbpHZM6nftnzLGF37cL2QCgpg4y fWBfcWoPaJzeLKg20jYieXE= =uL4V -----END PGP SIGNATURE----- ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
