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!
