I can chime in with the exact same error. I was using poudriere to build
some ports, and on apache-oo the machine actually had a kernel panic.
Machine has 16gb of ram and 16gb swap.

I had top running (update every 1 sec) and there was >10gb of swap free
when panic happened.

The OS is fbsd 9.1-PRERELEASE, from before problematic changes with
nullfs/zfs interaction.
