I've attached the dmesg output. I'm running memory and disk diagnostics
as it's strange that its only just started. (I haven't run a buildworld
in a week but only noticed the problem yesterday.)
Extracting a large tar file while the CPU is under load nearly always
triggers the problem. It's as if disk IO operations take longer and
longer until they eventually time out locking the machine. You can watch
the disk activity led go from constant to briefly flashing at increasing
intervals.
Buildworlds also gradually slow to a crawl but so far haven't resulted
in the vnlru_proc errors.
The first time it happened I was running "make -j 4 buildworld" on the
console and extracting the pkgsrc tarball to /usr/pkgsrc via a SSH session.
Regards
Gary
