[cobalt-security] too many files open?

["Matthew Nuzum" <cobalt@xxxxxxxxxxxxx>]

I just restarted apache because of some goofy things happening.  I had
caused an infinite loop with a PHP script that went awry.  Anyway, my log
check gave me some errors like this:

Mar 22 12:30:02 www in.qpopper[24750]: PAM [dlerror:
/lib/security/pam_deny.so: cannot open shared object file: Too many open
files in system]

Likewise /var/log/httpd/errors had errors about too many files open.

My infinite loop was a lot of queries to the postgres database, not
filesystem.

Would that have caused the above error and are there some other
implications?  Any advise apreciated,
