In principle, the results of ldapsearch should be comparable with diff
to see what's missing; then you should be able to look at the logs of
all the servers (and of the slurpds) and trace what happened to those
entries. If the entries don't get written/returned in the same order,
you may need to ldapsearch with -S "" (the empty string) to sort entries

Unless you provide indications as of to reproduce the problem, I suggest
you investigate as above. Also, you should specify what version causes
the problem; note that unless it can be reproduced with the latest
release, it is unlikely that it gets fixed or even traced to the root cause.
