I'm having a frustrating time trying to work out why our Dell PV124T (LTO4
autoloader with a Quantum drive) is not working well at present.
Kernel 2.6.33-2-amd64 on Debian
Bacula 5.0.2-1~bpo50 (customised)
The latest in a set of failures (can't write to tapes, can read reliably
off tapes) is as follows (from my kernel log):
[ 2517.323423] INFO: task bacula-sd:21475 blocked for more than 120 seconds.
[ 2517.323477] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables

Can anyone tell me what this means, apart from "your restore job just failed"?
Many thanks
