Re: vnlur_proc lockups under high disk I/O
: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.

What is likely happening is that the recycler is trying to flush out vnodes
related to things other then the hard drive, and one of those things is
causing it to stall.
Observe your other mounts carefully. What other mounts do you have?
