Re: kernel panic/paging error
I just saw it happen last night for the first time.

I caught it with a dozen M left in swap, had time to run ps, saw pflocal
had all the memory (>120M), killed it and it restarted. It cleared
about 65M from swap (I have 128M ram, 128M swap) which was still pretty
high, but it stabilized there. I have debian package libc0.2 at version
2.1.3-10 and hurd at version 20000921.
I also had 2 reboots (zalloc panic if I recall) where I guess I didn't
catch it soon enough.

Anything in particular to do to get useful information?
