I'm running a couple of brand new servers ... 32G of RAM, very little load on it right now, and this morning it locked up with that 'kern.maxswzone' error on the console ... The server is running a reasonably current 7.2-STABLE: FreeBSD pluto.hub.org 7.2-STABLE FreeBSD 7.2-STABLE #0: Sun May 31 14:48:04 ADT And top right now, with everything running, shows no swappping, 19G of Free memory, 9G of Inact memory ... no reason to do any serious amount of swapping. last pid: 32159; load averages: 0.12, 0.21, 0.47 up 0+10:57:56 11:53:39 573 processes: 1 running, 571 sleeping, 1 zombie CPU: 2.0% user, 0.0% nice, 1.2% system, 0.0% interrupt, 96.8% idle Mem: 1331M Active, 9446M Inact, 659M Wired, 35M Cache, 399M Buf, 19G Free Swap: 32G Total, 32G Free In fact, my other server (same config), has been up 9 days (they were put online 9 days ago), and tops shows it doing a little bit of swapping, but, again, huge amounts of Inact memory: last pid: 26307; load averages: 0.36, 0.35, 0.36 up 9+17:03:48 11:57:54 680 processes: 2 running, 657 sleeping, 21 zombie CPU: 0.7% user, 0.0% nice, 0.4% system, 0.0% interrupt, 98.9% idle Mem: 2915M Active, 25G Inact, 778M Wired, 13M Cache, 399M Buf, 1771M Free Swap: 32G Total, 1044K Used, 32G Free So these servers right now are definitely not feeling any pain ... And, based on experiences with another server, I have my /boot/loader.conf set to: kern.maxswzone=67108864 So, the question is ... what am I missing? Is there some magical formula for calculating maxswzone that 7.2 is missing? Some nagios plug-in I shuld be using to monitor ... what? Help? ---- Marc G.
