all right, here is my configuration:
backup-server is a P4 2,8GHz on a Fujitsu-Siemens Mainboard,
I knew that about the mainboard :-)
512MB RAM (upgrade to 2GB planned), 2 SATA disks for system
(soft-mirrored), Gigabit ethernet (3C996B-T with tg3 driver),
2 LSI 22320 (MPT Dual Ultra320 SCSI hostadapter) for connecting
2 Infortrend EonStor SATA-SCSI-Raids with 2TB (each).
Assuming you can't complain to a hardware manufacturer I'd recommend
stripping that down as much as possible.
For testing, I'd first drop the mirrored disk and use only one SCSI HBA
with one RAID system.
system is running Fedora Core 3 (all patches except last kernel
update 2.6.12-1.1376 as it won't boot with this smp-kernel),
mysql is 4.1.12 and bacula is 1.36.3.
Have you tried running a non-smp kernel? Probably even a standard kernel
from kernel.org?
when my system stops there are NO entries in any logfile, no
crash-dump after reboot and i've no idea what's going on when
it stops (it's totally frozen at this time, no output to console,
no input possible).
Have you tried SysReq key magic?
i'm monitoring the server with HotSaNIC and it also shows no
special problems before the server stops.
the only thing which is common for all times is that there are
4 or 5 of my heavy load backups are running at this time, so there
is much traffic on my network-card and also much traffic to both
Raids.
... and, of course, try another network card from another manufacturer.
but these backups run fine for 3 or 4 days and after that at the
next run the server stops....
Try to enable logging for all important device drivers and send the logs
to another host, too. Have a console active with a tail -f on the log
file while the system is running - sometimes that might tell you more.
And, most important, start to _really_ nag your hardware support staff ;-)
