Is this correct? I don't understand however, what Buf and Wired memory is used for. How many I free some of this up for use by my other processes? The top of my Top output looks like: 66 processes: 2 running, 64 sleeping CPU states: 1.5% user, 0.0% nice, 1.5% system, 0.0% interrupt, 96.9% idle Mem: 49M Active, 37M Inact, 27M Wired, 6000K Cache, 22M Buf, 5448K Free Swap: 256M Total, 5920K Used, 250M Free, 2% Inuse Yeah it's a fairly idle system but has a few stability issues which I think as disk related. It's running qmail, djbdns (may switch to bind but i know that would use more memory), apache 2, and some user apps like pine, irssi, screen, etc. Any advice on optimizin memory usage would be really appreciated. It's only a little P166 with 128Mb :-) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
