Too many open files

[Artur]

OS: FreeBSD6.2
PSA: 8.1.0

As soon as the server comes close to 400 domains (and sometimes even earlier) all hell breaks loose and we start to receive segmentation faults (sed fault (11) ) and "too many open files"

I've seen this
http://kb.swsoft.com/article_41_260_en.html

Since Plesk 8.1.0 builds everything from the Ports collection, I'm going to try to remove and reinstall all relevant ports, but I'm wondering if there is something else I'm missing.

here is my httpd-error.log
[Wed Mar 14 00:22:45 2007] [notice] child pid 14232 exit signal Segmentation fault (11)
[Wed Mar 14 00:22:48 2007] [notice] child pid 14216 exit signal Segmentation fault (11)
[Wed Mar 14 00:22:56 2007] [notice] child pid 14259 exit signal Segmentation fault (11)

also getting:
host: isc_socket_create: not enough free resources
host: isc_socket_create: not enough free resources

recompiled openssl and replaced the libraries just like the KB article says. then recompiled apache, php, and named. No joy, still gives errors. Could really use some suggestions.
