I've an OpenLDAP 2.4.32 server with millions of entries, which uses to serve tens of requests per second. It works as a stand-alone master server (replication is setup but the slave server is down) I noticed several times, at different times and dates, that no lines are logged in the OpenLDAP access log for a few minutes, as if it was frozen.
Any possible DNS problems? Do you have "reverse-lookup on" in your configuration?If yes, I'd recommend to always run a local DNS cache and/or disable reverse name lookups.
If no, I'd recommend to upgrade your OpenLDAP version. There have been many fixes and improvements during the last (almost) three years.
