For example, on my mail server (4.2-STABLE 2/27/01): kern.maxfiles: 8092 kern.maxfilesperproc: 2088 kern.openfiles: 332 This is normal, the machine has been up for 55 days with 0 problems. However, three times since installing this machine (4.1-R, 2 updates since), it's ran out of file descriptors, yet I could not find any processes to account for this behavior. So... my question is, how can I tune my FreeBSD 4-STABLE boxes to run a little more stable? I intend to update soon, I've just been putting it off in favor of running my business. FYI, I don't consider myself an amature admin... my previous employer has 2 3.2-STABLE boxes that have been running for 2+ years without issue (one is a mail server w/5000+ accounts, the other is a web server serving with an entire class-c bound to it, serving >280k hits per day). Any help or suggestions is appreciated, -- Troy Settle Pulaski Networks 540.994.4254 - 866.477.5638 http://www.psknet.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
