Title: Server locking up during backup
Post by: Nick on June 24, 2002, 02:41:25 PM
Hi all,

I have a rather severe problem.

I have a server which I recently converted over to act as the Domain Controller + File server for a small network of 4 computers. Before the E-Smith server was only running as a Firewall/Gateway.

Now I installed an old SCSI Card (Adaptec AHA-1524 - Using the aha-152x module) and a Sony 9000 (forgotten the full model number) Tape Drive.

Now when the server goes to backup at about 8:30 every night the server comes crashing down. No errors or anything it just ceases to operate.

This is what is showed in the messages log
Jun 22 20:30:00 server kernel: st: bufsize 32768, wrt 30720, max buffers 5, s/g segs 16.
Jun 22 20:30:00 server kernel: Detected scsi tape st0 at scsi0, channel 0, id 4, lun 0

Jun 22 21:00:01 server e-smith[1716]: S10mysql-dump-tables=action|Event|mysql-dump-tables|Action|S10mysql-dump-tables|Start|1024743$

after that nothing is logged until the server is hard booted?

Here is the flexbackup log if youre interested

I just troubleshot a very similar problem with my Dell PE2550.
It turned out that my SCSI controllers were sharing interrupts and causing intermittent lockups, always during a backup.  Try disabling anything that you're not using so that your motherboard can assign unique IRQ's to all the internal devices and see if it helps. ie com1/com2/lpt1/usb/mouse/ir/etc.

Mine does exactly the same thing that's why I came here hoping for a cure, did you figure it out in the end?

Simon.

After updating the bios and disabling every device not used, I haven't had a lockup.
