I've got an OpneBSD 3.7 machine (no patches - just the standard 3.7 CD install)
running under VMWare GSX Server V3.1 Today, the machine had stopped with a
panic. I did a "trace" and "ps" as per the instructions. Below is the result of
these extracted from /var/adm/messages after I rebooted the machine.
Jul 18 13:17:55 mx3 /bsd: panic: kernel diagnostic assertion "uvmexp.swpgonly
<= uvmexp.swpages" failed: file "/usr/src/sys/uvm/uvm_pdaemon.c", line 581
Jul 18 13:17:56 mx3 /bsd: Stopped at Debugger+0x4: leave
Jul 18 13:17:56 mx3 /bsd: RUN AT LEAST 'trace' AND 'ps' AND INCLUDE OUTPUT WHEN
REPORTING THIS PANIC!
Jul 18 13:17:56 mx3 /bsd: DO NOT EVEN BOTHER REPORTING THIS WITHOUT INCLUDING
THAT INFORMATION!

swapper
The machine runs the Exim mailer (www.exim.org) and SpamAssassin.
If it's usefull, the machine has 256MB RAM, with 512MB swap.
I tried a google, but only found reference to older versions of OpenBSD.
Is there anything else I should provide ? Anything else I should do if it
happens again ?
