This is your problem:
Jul 4 13:50:03 annuaire slapd[19523]: connection_read(18): no connection!
That is why it is deferring the operation. A quick google on that
shows some tuning of idle timeouts and possibly ulimit might be
helpful. I would recommend that you start tracking connections and
file descriptors to get a feel of conditions surrounding your
"freeze".
