Apr 3 14:31:48 canis41 slapd[122414]: conn=211822 fd=21 closed (idletimeout) in my logs for replica connections.
This indicates that there is an "idletimeout" directive configured and that the "limits" directive has not been configured for the replication DN to by pass that limit. The replication DN generally should not be subject to time or size limits.
