I thought so, but you did not mention it explicitely.

My machine has zfs, too. I do not have 8-stable with nfs on ufs, so I
cannot crosscheck that.

Mine is at 36k now:
36797/3403/40200 mbufs in use (current/cache/total)
35772/1202/36974/65000 mbuf clusters in use (current/cache/total/max)
35772/836 mbuf+clusters out of packet secondary zone in use (current/cache)

I think I'll reboot my machine now and hope that it lives as long as
possible into the weekend. Although at the present rate it will not
survive 24h. :-(
