  I left my cube running three Mathematica jobs last night and they
used up about 287 MB of swap.  One of them apparently finished after
a few hours and then a system panic window came up.  I wasn't at
the console, but had logged in from home and noticed two defunct
processes.  I looked at the "messages" and found the following:

Oct 15 18:21:29 mathnx lookupd[341]: netinfo sleeping: RPC: Timed out
Oct 15 18:21:35 mathnx lookupd[341]: netinfo waking
Oct 15 20:24:13 mathnx mach: zone "objects" empty.
Oct 15 20:24:13 mathnx mach: panic: (Cpu 0) zalloc
Oct 15 20:24:13 mathnx mach: Killing all processes .
Oct 15 20:24:17 mathnx mach: .
Oct 15 20:24:21 mathnx last message repeated 4 times

I had plenty of disk space left, about 100 MB or so free.  I couldn't
find any reference to "zalloc" or zone "objects" empty etc. in the
docs I have, so . . . what happened here?
