Looks like a filesystem panic. Could be anything from a corrupted fs that needs fsck run to an actual hardware issue in the hypervisor, or anything in between.
Those are hard to nail down in a virtualized environment.
Safest bet is to wipe+reload+restore config

Yeah, did that. The report should have been sent to your crash report recording service. Some info:

I suspect it must have been somewhere in the virtual block device layer, either the backing end or the communication between the backing disk and the block frontend in BSD, but most likely not a BSD fault anyway. Recording it here might help someone in the future. It runs fine now, and I couldn't reproduce this.

More information; 2.4 / FreeBSD 11.0 reliably crashes when more than 3 virtual network interfaces are added.

With 4 it generates a panic and dump, with 5 it just panics and hangs in kdb with db>.
