files-max is 297834
ulimit is 1000000

(doesn't make sense but there you go)

What I don’t really understand is with max_files_per_process at 800 we don't
get the problem, but with 1000 we do.

$lsof | wc -l
14944


$cat /proc/sys/fs/file-nr
12240   0       297834

There are only 30 connections - of those probably only 10 are really active.
It doesn't seem like we should be stressing this machine/

It would be less but then you can't maintain the db b/c of the constant
vacuuming needed :-(  I think the linux folks would get up in arms if you
told them they couldn't handle that many open files ;-)
