Hi All,
Our 7.2 system just paniced again in pmap_page_remove / uvm_fault:

(See also bug report from 24.4, subject: "kernel panic in pmap_page_remove")
After running fsck manually to clean one of the filesystems I did an
additional reboot, just to be sure the system would/could come up
cleanly.
I noticed this message on the console, seemingly as the system was
shutting down:
> stopping package daemons: nginx slowcgi postfix cyrus_imapd(killed) amavisd
> clamd sshguardreorder_kernel: failed -- see

That relink.log file looks like this:
> root:[~]# ls -ltr /usr/share/relink/kernel/GENERIC.MP/relink.log
> -rw-r--r-- 1 root wheel 142 Apr 30 14:29

What might that mean? Is it significant?
This is a virtualised OpenBSD instance running on QEMU / Debian Linux.
I've included some additional info, regarding the panic, output from ddb,
below ... if that is of interest.
Cheers,
Robb.
