Hello everyone. On one machine, and one machine only, the backup process
is crashing the server. In particular, it appears to be gtar that is
making it hang. This machine is configured similarly to every other
machine that I'm backing up, but this is the only one having problems.
Here is the error that shows up in /var/log/messages:

After this, the machine is fully hung, and I have to reboot it. I'm
thinking maybe gtar is hosing the stack somehow.
Any ideas? Or do I need to send this to the tar bug list? Here's the
stats on the server itself:
400MHz PII, 512MB RAM, RAID-5 SCSI with a DPT Decade card. Kernel
2.2.16-3, Amanda 2.4.1p1, gtar 1.12.
Thanks for any help!
