Doing a >'netstat -n | grep ^tcp' showed between 450 and 520 open connections, 1024 probably isn't enough, then. I'd recommend increasing it to 1500. Note that this will consume 6MB of memory. > Ummm... what should I be looking for, if I think I'm running out >of mbufs? Add up all the X's and see if they exceed NMBCLUSTERS? How "netstat -m" and make sure that the "mbuf clusters in use" remains well below NMBCLUSTERS. For instance: 17/44 mbuf clusters in use ...indicates that the kernel has allocated 44 mbuf clusters (escentially the peak usage since the system has been up) and that it is currently using 17 of them. The '44' will increase up to a maximum of NMBCLUSTERS. -DG
