That indicates that you've run out of mbuf clusters. You don't want to do that. You can increase the number with the kernel option: options "NMBCLUSTERS=<n>" Where <n> is a number that is several thousand. You can see the current peak since the system was started with "netstat -m" (the second number in the mbuf clusters ratio is the peak, not the limit). -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
