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: Name Mtu Network Address Ipkts Ierrs Ibytes Opkts Oerrs Obytes Coll de0 1500 00.e0.29.0e.b6.dd 668020 69 81086266 644829 3 753583880 74098 de0 1500 128.2 128.2.91.116 668020 69 81086266 644829 3 753583880 74098 ed0 1500 00.00.c0.77.bb.a8 2913267 6 482119730 3452395 0 1687583070 2226 ed0 1500 192.0.2 192.0.2.3 2913267 6 482119730 3452395 0 1687583070 2226 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.
