FWIW, I'm seeing the same thing on RELENG_6 by running ab
(apachebench) against localhost with nmbclusters set low (1024).
kern.ipc.nmbclusters=1024
debug.mpsafenet=0
ab -k -c 450 -n 10000 http://localhost/
netstat -m | grep mbuf
77789/236/78025 mbufs in use (current/cache/total)
1024/0/1024/1024 mbuf clusters in use (current/cache/total/max)
502/0 mbuf+clusters out of packet secondary zone in use (current/cache)
vmstat -z | grep mbuf
