OpenLDAP 2.0 is very old (circa 2000) and being 9 years old is going to give you problems.
It sounds like your problem is session based, and it may be your client has left a connection open but the server (TCP) has closed the session and has not told the client to close the TCP session.
First step for you - upgrade.
