I commented about this a day or few ago, but at that point I was still
chasing other possibilities, so here I go again 8)

I have a reasonably -curent system that, under moderate load is dying 
after about 18-20 hours of uptime.  The system itself is a P120 on a
Triton board with 64M and an NCR PCI controller :

FreeBSD mstradar.esrange.ssc.se 2.2-CURRENT FreeBSD 2.2-CURRENT #0: Mon Jul 15 13:16:26 MET DST 1996     msmith@spore.atrad.adelaide.edu.au:/usr/work/radarsys/compile/MSTRADAR  i386

The system is being pushed fairly lightly, although there are some long-lived
processes that accumulate a lot of CPU (and have largeish swap footprints).
These large processes are all Linux a.out binaries (IDL).

Symptoms are that the system remains pingable, and you can often get 
through the telnet login sequence to the point where /usr/bin/login
is invoked but no further.  As I type, the system just died under me again;
I was watching the output of 'systat -vmstat', quit and typed 'w' to check 
the load.  I got this :

mstradar:/home/radar>w
 5:04AM  up 19:28, 2 users, load averages: 0.00, 0.00, 0.00
USER     TTY FROM              LOGIN@  IDLE WHAT

and then nothing more.

There have been no console or syslog messages to date from any of the
times that this has happened.  Any suggestions as to where to start
looking would be appreciated; unfortunately due to the rather remote
location of the system I can't play DDB with it 8(

Help?
