The procedure follow is fully repeatable with consistent problematic results for me.

Unable to reproduce this on Linux using RE24.

(1) ftp://ftp.openldap.org/pub/OpenLDAP/openldap-release/openldap-2.4.43.tgz, installed via osx homebrew with configure flags --prefix=/usr/local/Cellar/openlp%p/2.4.43 --sysconfdir=/usr/local/etc --localstatedir=/usr/local/var

(2) config and related files as uploaded on the given URL (cosine.schema is unedited but included for completeness)

(3) /usr/local/var/openldap-data/ is empty

(4) sudo /usr/local/opt/openldap/libexec/slapd -d 255 -u peter 2> slapd.log

(5) ldapmodify -D 'uid=peter,o=habbie' -w secret -c < named.conf.ldif 2> ldapmodify.log ; ldapdelete -D 'uid=peter,o=habbie' -w secret -r ou=dns,o=habbie 2> ldapdelete.log modify is unhappy, initially because of some unknown attributes (thish is why I used -c), then later because it is hitting the MDB maxsize of 10 megabytes. ldapdelete then fails to delete the ou=dns tree due to MDB errors

(6) increasing maxsize after this 'corruption' has happened does NOT enable ldapdelete to suddenly work

ldapdelete works fine for me after raising maxsize.

(7) (with slapd stopped, not sure it matters): $ /usr/local/opt/openldap/sbin/slapcat outputs 191771 lines to stdout before aborting with: 56a63063 mdb_entry_decode: attribute index 24 not recognized Segmentation fault: 11

Never saw this, slapcat runs to completion with no complaints.
