I didn't get all of that one (syslogd died and I rebooted before grabbing
it from dmesg).
Here's another one, though:

And here I thought it was a NIC issue.
This was compiled with
gcc version 2.95.2 20000220 (Debian GNU/Linux)
No SMP, no module support, optimized for PII/Celeron.
No swap had been used when it died.
