[suse-security] k_deflt-2.4.18-262 and Legato Networker -> system is dead

["Ralf Gross" <Ralf-Lists@xxxxxxxxxxxx>]

Hi,

last monday I updated the kernel of our Suse Linux 7.3 server
(k_deflt-2.4.18-262.i386.rpm, compaq DL380).
After that, the server died every night, just after Leagato Networker
backup software contaced the server.

I can't see anything useful in the logs. The last entry in
/var/log/messages is at 22:59h, the backup beginns at 2300h. The first
night the server died, Legato was able so backup some stuff, but died at
2320h.

I could ping the machine and got a connect on port 22 (ssh), but no
ssh-banner or anything else. I had to reset the machine.

I used a tool called stress to test the server. I generated a load of 10
for  about 1h - no problem. I also used this tool, and bonnie, to stress
the hard disks - no problem.

Then, I fall back to the original kernel that came with 7.3. Now
everything works normal again.

Any ideas what went wrong?

Ralf
