The above mail has a backtrace involving ZFS.

I'm running the periodic scripts serially now, 8 out of 14 already
finished without issues. Smells like a concurrency issue. I would
assume it's something introduced between 5 and 1 month ago and MFCed
back to 10.

Does this ring a bell for someone on fs@?
