Problem replicating ACL changes in back-config from master to slaves: SEGFAULT

Hello list,

I created a ldap master serving a ldif-db cn=config,cn=server for a bunch of slave servers replicating their config with suffixmassage cn=config.

The master is 2.4.25 and the slaves are 2.4.25 and 2.4.26.

If I change ACL's in the db definition of a bdb database at the master db cn=config,cn=server all slave servers segfault with:

Error: closing the transaction region with active transactions slapd daemon: abnormal condition, shutdown initiated.

slapd shutdown: waiting for 2 operations/tasks to finish Segmentation fault

Any hint?

Regards Uwe
