Too many open files

[Hinst, Robert]

Running bind-9.3.6-4.P1.el5_5.3 on CentOS 5.5 and I'm constantly seeing the following in my BIND logs:

general: error: isc_socket_create: fcntl/reserved: Too many open files

But I don't see why. Named only has 583 files open and I upped the max to 90000 in /etc/security/limits.conf. Has anyone encountered this before or have any insight?
