I take this back. The slapd server is fine, but my system ran out of 
available sockets. I don't think this is a relevant problem - the reason 
the client usually hangs after about 28,000 connections is because all 
of the TCP ports are used up by then, the old ports are still in 
TIME_WAIT and the client can't make any new connections at that point.
