When the server was switched to SMP the problem became less common, but raising the MaxClients in apache above 256 brings the problem back consistantly. In the kernel config, NMBCLUSTERS=4096 and here is the output of netstat -m: 4856/5216 mbufs in use: 3365 mbufs allocated to data 1491 mbufs allocated to packet headers 3044/3250/4096 mbuf clusters in use (current/peak/max) 7152 Kbytes allocated to network (93% in use) 0 requests for memory denied 0 requests for memory delayed 0 calls to protocol drain routines Does anyone know how to make more mbufs available or know how to reduce the number of mbufs in use?
