ldapsearch gives partial results

[Emmanuel Dreyfus <manu@netbsd.org>]

Hello

I have a problem with ldapsearch sometimes returning partial results.
The result code is still 0 (success), but the list of object is limited
to 63 or 127 (it seems there is a 2^n-1 pattern) items instead of expected 
136. It will happen after 10 to 15 requests that return the complete result.

The filter is below. It can happen even if only DN are requested (no 
attributes):
(&(|(ou=example1)(ou=example2))(objectClass=netExamplePerson)
    (!(netExampleHidden=TRUE))(netExempleActive=TRUE))

This is OpenLDAP 2.4.40, BDB 4.8.30. All attributes in the filter are
indexed, and it happens after the openldap-data directory has been 
cleared and everything has been reconstructed from scratch.
