Hi, We ran a performance run on our application. With 20 users hitting the application we got this error in logs. 1) What operations in LDAP cause fds to open and exceed the limit specified? 2) If i use connection pool in my application to connect to LDAP will that get rid of the problem?

Chances are your maximum file handles are set far too low (which probably caused a warning at install time). http://directory.fedora.redhat.com/wiki/Performance_Tuning#Linux
