(In reply to Mark Johnston from comment #4)
To expand on this, the pattern of stack traces look very much like a degenerate
behavior in the UMA memory allocator when the per-cpu caches are empty, and the
allocation must go back to the zone, and you wind up taking a lock on every
allocation.
I'd check to see if there is a mbuf leak. The output of vmstat -z would be
helpful here.
