Re: kern.maxfiles questions
Some updates to this. The machine was unresponsive this AM so I had to reboot it. I'm used to 90-100 day uptimes (as the power company permits) so this is quite unusual.

Already it's at almost 3000 (from less than 300 when I first noted it), so I assume I'll hit 4040 before too long. and on further examination I am finding some swap shortages (this machine has 512 Mb of real memory but only the same amount of swap). I actually only have 256 Mb of RAM with a half gig swap partition. I added another 512 Mb swap file and I am monitoring swap vs real mem usage as well (http://www.paulbeard.org/mrtg/red/red-mem.html). if this is all I need to do, I guess that's OK, but I'm still not sure why it became an issue all of a sudden.

kern.maxfiles questions
I'm still having some issues with file descriptors being used up. Symptomatically, my http listener will become sluggish and some cgi processes I use will time out. The logs have a raft of these messages: Dec 27 22:46:13 red /kernel: kern.maxfiles limit exceeded by uid 80, please see tuning(7). Dec 27 22:47:12 red /kernel: kern.maxfiles limit exceeded by uid 1004, please see tuning(7). I can't even query sysctl, but after stopping httpd and postfix (the processes being run by those UIDs) I can finally get this information. [/usr/home/paul]:: sysctl kern.openfiles kern.maxfiles kern.openfiles: 257 kern.maxfiles: 4040 and on further examination I am finding some swap shortages (this machine has 512 Mb of real memory but only the same amount of swap). what tunables can be twiddled, assuming swap doesn't solve this?
