I thought I would through this into the mix:
Server, NOT in production yet: 4.1.1-RELEASE:
matt[beta]:~> uptime;netstat -m
10:40AM up 16 days, 1:42, 2 users, load averages: 0.00, 0.00, 0.00
132/352/131072 mbufs in use (current/peak/max):
130 mbufs allocated to data
2 mbufs allocated to packet headers
128/316/32768 mbuf clusters in use (current/peak/max)
720 Kbytes allocated to network (40% in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines
Heavy Use Workstation, 4.1.1-RELEASE:
10:42AM up 16 days, 49 mins, 9 users, load averages: 0.28, 0.20, 0.17
693/1712/131072 mbufs in use (current/peak/max):
132 mbufs allocated to data
561 mbufs allocated to packet headers

0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines
So what you're showing below looks pretty normal. Note: I KNOW that I have
a small leak on epsilon. It's from wmbiff, which holds up descriptors like
you would believe. Gotta shut it down every couple of weeks to clear it
out, it's quite funny. Just to give a roug idea:
root[epsilon]:~# lsof -p 98037 | wc -l
3225
Oh well. :)
