[K12OSN] OT: Openldap and too many open files

My ldap server is now failing with the
slapd: warning: cannot open /etc/hosts.deny: Too many open files
message. I have 100+ teachers and an additional 150+ students
connecting at any given time. I run nscd on all my systems since this
is a suggested solution for reducing the load and consequently the
open files on the ldap server(s).
I can restart ldap and it will run for a bit before issuing this
warning at which point all authentication stops. I've googled for
solutions and most suggest using ulimit in the ldap script to set the
file limit higher. I have done so but it doesn't seem to make the
change. Other responses on this suggest that I may have to recompile
openldap and possibly nss related items as well to get around the
issue. That is a daunting issue.
I have also seen a suggestion to set the idletimeout in slapd.conf but
I am not sure that this wouldn't adversely affect anything since it
Has anyone else seen this issue and implemented a solution?
Has anyone else seen this issue and found a good solution to it?
