It's caused by an insufficient number of mbuf clusters being available. You can increase the mbuf cluster pool size with options "NMBCLUSTERS=1024" (or 2048 or whatever if necessary; each cluster takes 2K of memory). Newer versions of FreeBSD (including 2.0.5R), have a more dynamic calculation for this which is based on maxusers. -DG
