[rhn-users] Sudden system restarts

[GREG WOJTAK]

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".
I did this with other shells running top, and vmstat 1, this was the
last thing printed on those shells:

  2:47pm  up 31 min,  5 users,  load average: 1.36, 1.37, 1.00
79 processes: 78 sleeping, 1 running, 0 zombie, 0 stopped
CPU states:  9.7% user, 25.6% system,  0.0% nice, 64.5% idle
Mem:    57608K av,   52724K used,    4884K free,       0K shrd,   
6040K buff
Swap:  240964K av,       0K used,  240964K free                  
31444K cached

The hardware watchdog is shut off.
There is no evidence in /var/log/messages nor /var/log/dmesg.  I don't
know where else to look.
Swap is unused and plentiful.

Wanted: clues about utilities to run, switches to set on, etc. when
causing this catastrophic reset.
