I haven't played with vm.kvm_free, but I do run with 65536 mbuf clusters. Hrm... this is outside of my expertise. I have 4.X boxes running with 130K mbuf clusters (and I actually need to find a way to increase this further!) so this is definately something I'll run into and likely others will when they update their production boxen. Is this a sysctl data presentation issue? -sc -- Sean Chittenden To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
