help needed with LDAP update errors



We've been using OpenLDAP 1.2.x for more than a year to store
descriptions of document services. Today, while testing our code we
seem to have screwed up the database, or its indices, or both. 

Current setup: Sleepycat db-2.7.7 
	       OpenLDAP 1.2.9

The scenario that seems to have caused the problem is the following:

1. Application on client 1 is repeatedly listing all entries on a
subtree and then  deleting and then immediately adding an entry on the 
same subtree

2. Application on client 2 is doing the same but with a different
entry.

I did an ldbmcat and rebuilt indices (didn't seem to help, but maybe
I'm not doing it right).

Any suggestions on what's up and what to do are appreciated. My
hypotheses include
   (1) threading problem with simultaneous updates from more
than 1 client
   (2) some problem with DB2 database
   (3) some problem with LDAP
