Okay, well...NetBSD froze again last night. It was frozen for about 8
hours (there was a running clock on the screen, so I knew excatly what
time it froze).

This time, I did a trace and wrote down the results:

db> trace
_Debugger(d51ba,5764a,7ffbd0,32be,2) + 6
_nmihand(2,cbf7c9cb,21042c,2) + 26

_sys_select(6b26f00,7fff88,7fff80) + 250
_syscall(5d) + 13e
_trap() + e
db>

There it is, in all it's enigmatic glory :)

I hope this helps someone solve this most mysterious problem. Upon
freezing last night, the box had been up without freezing for about 2
days. So why is it freezing all of a sudden in seemingly random intervals?
I don't get it.

Oh, BTW, after the new db> prompt, it freezes again, and I can't type
anything on the prompt, and interrupt switch doesn't bring it back...

Thanks a lot for all your help!
