Thanks for the info. One question remains. Suppose netstat -m tells me that 7900/8050 mbuf clusters are in use. Now suppose I stop all of the important processes and let the machine stay idle for 2 hours. Why does netstat -m still tell me that 7900/8050 mbuf clusters are in use? Basically, I'd wish it would say something like 99/8050 mbuf clusters in use instead. I already have MAXUSERS set to 512.
