I had this with an older version of OpenLDAP and BDB (hdb) backend. The problem was that a remote database was not completely in sync. So I shut down remote slapds, removed the databases, dumped the database of the remaining master and slapadded them on the shutdown nodes. Then I started up those noedes, and everything was fine since then.
