Hi, I just made my 2.1.5 box run out of mbufs:

kernel: Out of mbuf clusters - increase maxusers!

so I thought I'd let it rest and wait for things to expire...

(a reboot is going to be necessary, I can see...)

however, netstat -m now looks like this:
1038 mbufs in use:
	1025 mbufs allocated to data
	2 mbufs allocated to packet headers
	3 mbufs allocated to protocol control blocks
	8 mbufs allocated to socket names and addresses
1024/1024 mbuf clusters in use
2177 Kbytes allocated to network (100% in use)
0 requests for memory deined
0 requests for memory delayed
0 calls to protocol drain queues

there appear to be no outstanding connections in netstat -an output.

To get the machine in this state, I was using it as the source of running
iptest against an UltraSparc2 (making heavy use of sending packets out via
BPF).

Some minutes later, "netstat -m" still reports the same.

Reboot time I guess: new kernel and has been up less than half an hour.

Darren
