Can you be more specific? If you run out of mbufs, the system usually panics. You can fiddle with the NMBCLUSTERS option in the kernel config, but be warned: this takes out of kernel virtual memory, and it's quite possible to exhaust KVM and get all sorts of wierd crashes if you set it too high. If you need to increase the KVM size, there are some options to tweak it, but I don't know them. I'm sure that some in the FreeBSD community would be happy to tweak your system, for a fee. :-) Doug White Internet: dwhite@resnet.uoregon.edu | FreeBSD: The Power to Serve http://gladstone.uoregon.edu/~dwhite | www.freebsd.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
