We need more info before it can be detemined that there is a "leak". The machine is trying to do more than 8 million connections/day, and there are special considerations when trying to do that. 10000 mbuf clusters almost certainly will not be enough. He may not be able to configure enough, in fact, without changing the kernel VM layout. -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
