Is anybody else seeing this?

lab:/root # netstat -m
4294959731 mbufs in use
1170/25600 mbuf clusters in use (current/max)
0/3/6656 sfbufs in use (current/peak/max)
448 KBytes allocated to network
0 requests for sfbufs denied
0 requests for sfbufs delayed
0 requests for I/O initiated by sendfile
650 calls to protocol drain routines
lab:/root # uname -a
FreeBSD lab.databus.com 6.0-CURRENT FreeBSD 6.0-CURRENT #0: Fri Dec  3 21:44:57 EST 2004     toor_at_lab.databus.com:/usr/obj/usr/src/sys/LAB  i386

It happens almost instantly during periodic when the system is used to
receive a backup via nfs.  Normal operation, including a dozen hours of
port building, does not cause it.  It is consistent, 3 times now.

H/W is Asus A7M266-D with 2xAthlon 2200MP, 1GB, 39160, gvinum, em.

Problem did not occur with prior -current from 11/19/04.  Other than cvsup,
I changed make.conf to say CPUTYPE=athlon-mp (was i686 or nothing).

What can I do to help debug this?
