The FAQ could be wrong. On my IRC box, I have my mbuf's at 17,000 actually. (you should find out what the max mbuf's it's gonna use with netstat -m at various intervals, then double that figure). And I remember seeing a post from DG saying something about ftp.cdrom.com having 80,000 mbufs..

According to the FreeBSD FAQ, http://www.freebsd.org/FAQ/FAQ92.html, "NMBCLUSTERS=4096" is the maximum. -- :{ andyf@speednet.com.au Andy Farkas System Administrator Speed Internet Services http://www.speednet.com.au/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
