(ITS#5275) Poor LDAP performance when we reach 1000 connections

We're using a Red Hat EL 4 release 4 box to run openLDAP version 2.3.32.
Every night we find ourselves reaching  1000+ (netstat | grep ldap | wc -l)
connections to our LDAP server and have found the only resolution to restart the
LDAP service daily. When we get to 1000+ connections performance takes a huge
hit and no one is able to login to any box utilizing LDAP. This server consists
of 2 dual core Opeterons with 8 GBs of memory, so its not a hardware performance
We're able to duplicate this issue on a RHEL 4 release 5 box also when we reach
1000+ connections using the same config files. Is there a setting that needs
adjusting so connections timeout or some other config file misconfiguration?

Any help would be much appreciated. 
Thank you.
