I had configured an mdb backend with a unique overlay configured like this:

add olcOverlay={4}unique,olcDatabase={2}mdb,cn=config objectClass: olcOverlayConfig objectClass: olcUniqueConfig olcOverlay: {4}unique olcUniqueURI: ldap://?supannAutreMail?sub

When trying to add the first non root-entry of new DB openldap freeze and takes 100% CPU. After activating loglevel 255 I saw that it was looping inside mdb_search() logging 'scope not okay' with an increasing integer value in front.

Looks like a duplicate of ITS#8146, fixed in the OPENLDAP_REL_ENG_2_4 branch. Please test. Tarball: http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=snapshot;h=refs/heads/OPENLDAP_REL_ENG_2_4;sf=tgz

We might need a more general description of ITS#8146 in CHANGES.
