Have a look at the output of netstat -m, see if there is a problem with the usage of mbuf cluster usage. You might need to add something like OPTIONS NMBCLUSTERS 65536 to your kernel config and rebuild + reinstall the kernel. Or, I could be completely wrong, if so I apologise in advance :) Regards, Philip Brennan
