Try with configuration parameter conn_max_pending (number of connections waiting for processing thread) conn_max_auth (same, but for authenticated) If you are using anonymous auth then, by default you have conn_max_pending=100. In your configuration I don't see need to increase threads to 32? Does your open ldap has PostgreSQL backend? :) Try to increase open ldap log level - to get info about connection opening. -- ---------- RadosÅaw Smogura http://www.softperience.eu David Kerr <dmk@xxxxxxxxxxxxxx> Monday 06 December 2010 18:00:19 > The problem is, i'm not seeing a corresponding error on the OpenLDAP side. > > Also, it seems like this only happens under load, like if someone does a > unit test that connects to the database 100 times in a few seconds. > > Has anyone dealt with this?
