There is no reason to stop LDAP if you are using back-bdb or back-hdb
(and if you are using back-ldbm you are also crazy).

But you might want to do a:
su ldap -c "/usr/bin/db_checkpoint -1 -v -h /var/lib/ldap"
... prior to the backup, and it doesn't hurt to do one periodically
anyway (especially with OpenLDAP 2.2.x).
