[rhn-users] Sudden system restarts

[Brian T. Brunner]

service netdump start
fails, can't locate module netconsole
?Kernel sources?
netconsole does not appear anywhere in /usr/src/linux-2.4.18-3 in upper or lower case...

on the server side you need to set a password for the netdump user, run
netdump --propagate, and then lock the netdump account back out.  At
least that's what I've done in the past.

netdump is there.

The netdump crash host can run netdump-server, and can run netdump
--propagate as a client to itself as server.
The target startup of netdump --propagate dies on authentication
(publickey,password) when the password given works for ssh, rsync, etc.
There's some magic involved in the key management there.. hints?

RH7.3 (shrike).  I'll look for netdump anyhow.

Other thoughts?

Is this RHEL?  If so, can you try setting up a netdump server?

Running: a large application in a small (64MB) system.
Symptom: sudden system restarts (as if by watchdog hardware reset)
Method to trigger: when the system runs well, open (another) ssh shell
and execute "makewhatis".
