An OpenLDAP server is experiencing timeouts during peak usage. The administrator notices that the server has many idle connections but is rejecting new ones. The server has 4 CPU cores. What is the most likely cause and the best fix?

The connection limit is too low; increase the sizelimit directive.

The checkpoint interval is too short; increase the checkpoint directive.
