Hello,
when I have two ldapserver (master/slave with delta syncrepl) and do insert on
the master while the slave is down and then start the slave, only some entries
get replicated. 
This problem is reproducable (every time). I did my test with a build of 2.4.25
and mingw and with 2.4.41 build with visual studio. The version 2.4.25 is 32 bit
and the 2.4.41 is 64 bit. Operation system is Windows. Version 2.4.25 runs with
hdb, version 2.4.41 with lmdb.

Here is a description in detail:
Master and slave are fully synchronized. Then I stop the slave. Add 100 users to
the master LDAP. I wait a few seconds, then I start the service at the slave. 
Now only some users get replicated. 

Here is my configuration of master (of the hdb try):
