'netstat -m', watch these lines: 131/864/10240 mbufs in use (current/peak/max): 128/172/2560 mbuf clusters in use (current/peak/max) You want to keep the second number about 80% of the third number. If it gets too close bump the kernel tunables kern.mbufs and kern.nmbclusters (or set options MBUFS and NMBCLUSTERS in the kernel config).
