SC1425 Server Hangs

[Gareth Bult]

Hi,

We have a number of SC1425's, one in particular runs as a thin client
sever.
(Ubuntu 6.06 LTS / LTSP)

Approximately once a week, it hangs.
For one reason or another (remote site) I've not been able to see what's
on the console when it goes down and there's nothing in the logs when it
comes back up. (reset button)

When it's down, various ports "respond" in terms of connections
apparently opening, but no applications activate on the box.
(i.e. can connect to port 22 on the server, but there is no response
beyond the connection)

Server responds to pings.

Config is dual-2.8G Xeon, (dual core), 4Gb RAM, single disk, NFS mounted
home.

Box goes down when (relatively) lightly loaded.

Other non-dell servers, same sort of config and /home NFS mount continue
unhindered.

So, not network, not nfs, not load .. anyone got any ideas ?

tia
Gareth.
