Replication of our ldap database often stops working, with pending changes stacking up and not getting processed by slurpd. /var/lib/ldap/replog (as configured in slapd.conf by the "replog" directive) fills up with entries, and slurpd doesn't pick up on them.

That's pretty much the reason why syncrepl was invented/implemented in OpenLDAP 2.2 and slurpd is deprecated and abandoned from 2.4.

Likely everybody here will simply recommend to migrate to syncrepl.
