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.

I raised the kern.maxfiles to 16383 and am monitoring it with mrtg 
(http://www.paulbeard.org/mrtg/red/red-openfiles.html). 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.

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.

Is there some way to find out what's tying up the file descriptors?
