I have rebuilt the kernel and increased the maxusers parameter from 32 to 64, and yet the netstat -m output always indicates high usage by the network (Please see the output of the netstat -m command below). Increasing total RAM to 256 MB, or adjusting the maxusers or nmsclusters parameters doesn't seem to affect this percentage usage. I still have problems with mbufs not being available at times when the system is under heavy load. Can anyone advise me if there are any tuning parameters to allow more memoty usage for the network? Any and all help is greatly appreciated!
