IPX system crash (no log data)

[AGC <agcarver+netbsd%acarver.net@localhost>]

Hy everyone,

I'm trying to figure out the cause of a system crash/halt and am having 
quite a bit of trouble so I could use your advice.

This is the IPX that is running just ntpd plus the PPS enabled Generic 
kernel.  Nothing else runs on the system but it seems that after about a 
week of running, it just stops.  It is unresponsive to network 
connections and the console doesn't respond either (sitting at the login 
message).  I have to Stop-A and boot to restore the system.

None of the normal logs (messages, cron, etc.) and seem to indicate 
anything out of the ordinary.  No messages are emitted on the console 
either.  Are there any other logs that NetBSD maintains that might give 
me a clue about what happened?

THanks
