So, like Francesco Casadei was saying to me just the other day:

Yep, low mbufs. Good question. It shows:
www 1429 # netstat -m
137/1248/4096 mbufs in use (current/peak/max):
131 mbufs allocated to data
6 mbufs allocated to packet headers
129/1024/1024 mbuf clusters in use (current/peak/max)
2360 Kbytes allocated to network (76% of mb_map in use)
180 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines
This is currently a semi-quiet network. Is most of that 76%
now dead space?
At least we're not freeing free mbufs!
