 I believe this is a known issue on SMP systems.  Robert Watson posted
 a patch on the current@ mailing list around November in response to a
 similar report by Andrew Gallatin (synchronizing the mbuf counters has
 performance penalties though).  Can you confirm that if you use that
 patch the problem goes away?
