You still are not explaining why the current code is wrong. You say "bogo-vnode". Please explain what that means. What does "in a pinch" mean?? What do those numbers in kern.malloc mean?? I've had only one experience in the five years ive been running FreeBSD in my production environment when swapping has had an affect on normal the production environment - a mail server that only had 32M RAM and wasnt tuned properly, one time decided to spawn a dozen or so children each time the client connected and got kicked off because we have a 5 minute redial-policy... anyways, the box had so many processes running (sendmails) that the physical disk couldn't keep up with demand. I sat at the console for an hour watching the disk-busy LED full on for an hour while trying to recover from what was happening. I eventually pushed the 'reset' button and hoped for the best. Please, I know you are are God and are way above me, but try and be gentle to us lowlife scum that populate userland..... -- :{ andyf@speednet.com.au Andy Farkas System Administrator Speednet Communications http://www.speednet.com.au/
