Perhaps just setup a cronjob... vmstat -m >> /var/log/vm.out But have a look at your busier times to see if the High Use is getting dagerously close to the limit. Do you have a lot of aliased IPs on this box by any chance ? As its an IRC server, its no doubt subject to various attacks. Check to see if there is any ICMP funny business being blasted at you like a few million ICMP redirects. ipfw and sysctl can be your friend here. ---Mike ------------------------------------------------------------------------ Mike Tancsa, tel +1 519 651 3400 Network Administrator, mike@sentex.net Sentex Communications www.sentex.net Cambridge, Ontario Canada To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
