I probably don't run into this, as I already have maxusers set to 192. :)
Which is probably overkill, but once in a while it may prove useful.
The server is fairly busy (but not cdrom.com busy :). It has two
interfaces, one de0 and one ed0 (both SMC cards). As of the 13 hour
uptime, the following is netstat -nbi output:

The current mbuf situation seems reasonable:
537 mbufs in use:
411 mbufs allocated to data
110 mbufs allocated to packet headers
12 mbufs allocated to protocol control blocks
4 mbufs allocated to socket names and addresses
266/458 mbuf clusters in use
983 Kbytes allocated to network (60% in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines
But I don't have statistics from before the stable- upgrade.
