hello there,
 Since your script is run by cron every one minute, i wonder that do
you have any lock mechanisms to prevent more than one instance of your
script to start? some buggy or mis-configured ldapserver can not work
properly when large amounts of write operations come simultaneously.
 What I suggest is carefully re-design your script. use some lock
mechanisms and some queue technologies.
