send_search_entry: conn xxx ber write failed

Good morning. How are you doing ?

Guys, I have a application that do many connections to my ldap server and I am getting the error "send_search_entry: conn xxx ber write failed." and "(connection lost on write)".

This error occur only with that application, but The noise is large, because this one is very importante.

So, Do this message mean a problem with my LDAP Server? Will I need deploy a other LDAP server and balance these connections ?

Thanks for the help!
