What version of BDB are you using?  Have you configured a checkpoint in 
slapd.conf?  What version of OpenLDAP are you using?

There were some bugs in some versions of BDB and I think some version of 
OpenLDAP that failed to properly checkpoint, causing the issue you are 
seeing.  A properly patched version of BDB and a current release of 
OpenLDAP should certainly not have this problem.
