8.4-p23 zfs panic

[Charles Sprickman]

Howdy,

I have a box that had been running 8.4-p1 for about a year and a half with no issues.  Pretty standard 2U Supermicro box, ZFS-based setup with a few jails.  Mainly used to store backups and other utility tasks.  Most backups happen with rsync, but two vmware boxes nfs mount this host and dump snapshots to it.  It also runs poudriere builds when that time rolls around.

Two days ago I updated to 8.4-p23.  I ran a few large poudriere builds the night before last, and then queued a few more last night.  Overnight the box paniced (and in the annoying way where it does not automatically reboot nor generate a dump).

Any known issues that I’ve missed?  What sorts of zfs changes have gone on between p1 and p23?

Wish I had more info, but without a dump, I don’t know what else I can share.  I think it’s safe to assume a poudriere build was in-progress, finishing, or starting when the panic occurred.

Automatic reboot in 15 seconds - press a key on the console to abort
