Is it possible that that application is pro-actively creating LDAP connections that it does not use? This scenario might happen if the application is using connection pooling.

Subject: [389-users] Re: Connections Opened but No BIND Received
Happy New Year, everyone!
Further to this, I added connection management loglevel to the errorlog level and managed to capture the output during one of the events when the connection seems to stall. Would anyone be able to help me make sense of it?
Thanks a lot,
Trevor Fong
