It looks like some ldap clients keep the connection to the apachds alive.
Where are those log files coming from ? Which version of the application ?
Also not that if you are on linux, the default number of handles you can
open is 1000, which is far too low for a LDAP server, assuming you might
have ten of thousands opened connections. Tune your system.
