Re: IPX system crash (no log data)

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?

so, when you use stop-A what prompt comes up?  db>  or ok?  from
here, you can get more info (either one) but it depends on which.
if it isn't ddb (db>) then it might be better to build a kernel
with DDB enabled and go from there.

from "db>", you can type "bt" to get a back trace.  from "ok" you
should be able to "ctrace" to get the same, but i don't remember
what the IPX firmware supports.

I get the OBP "ok" prompt. I'll keep an eye on it (right now I've rebooted) and then if it drops again I'll post ctrace results. If that doesn't result in useful data I'll recompile with DDB.

Judging from the messages log, it will be about eight days before it crashes again.
