crazy server crashes
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi all,
I'm experiencing heavy lenny crashes from time to time.
Kernel is still working (at least responding for pings and continuing
processes which has been started earlier).
Only available piece of information I can have from it is a console
notifications via ilo. Cause logging in doesn't work either via ssh or
console.
Machine is unresponsive and console is displaying only something similar
to this:
[10097664.608378] INFO: task sshd:23029 blocked for more than 120 seconds.
[10097664.608445] "echo 0 > /roc/sys/kernel/hung_task_timeout_secs"
disables this message
Sometimes it appear that I can log in via ssh and use magic system
requests to force 'save' reboot, but it's very rare usually I have to
take it down in a brutal way.
It's a remote server so physical access is rather hard (read impossible)
Any advice how to investigate further will be appreciated and solution
for this even more :-)
thx ladys and gents
