[389-users] Crash with SEGV after compacting

Hi My organisation is using a replicated 389-dirsrv. Lately, it has been crashing each time after compacting. It is replicable on our instances by lowering the compactdb-interval to trigger the compacting: dsconf -D "cn=Directory Manager" ldap://127.0.0.1 -w 'PASSWORD_HERE' backend config set --compactdb-interval 300 This is the log: [03/Aug/2022:16:06:38.552781605 +0200] - NOTICE - checkpoint_threadmain - Compacting DB start: userRoot [03/Aug/2022:16:06:38.752592692 +0200] - NOTICE - bdb_db_compact_one_db - compactdb: compact userRoot - 8 pages freed [03/Aug/2022:16:06:44.172233009 +0200] - NOTICE - bdb_db_compact_one_db - compactdb: compact userRoot - 888 pages freed [03/Aug/2022:16:06:44.179315345 +0200] - NOTICE - checkpoint_threadmain - Compacting DB start: changelog [03/Aug/2022:16:13:18.020881527 +0200] - NOTICE - bdb_db_compact_one_db - compactdb: compact changelog - 458 pages freed dirsrv(a)auth-alpha.service: Main process exited, code=killed, status=11/SEGV dirsrv(a)auth-alpha.service: Failed with result 'signal'. dirsrv(a)auth-alpha.service: Consumed 2d 6h 22min 1.122s CPU time. The first steps are done very quickly, but the step before the 458 pages of the retro-changelog are freed, takes several minutes. In this time the dirsrv writes more than 10 G and reads more than 7 G (according to iotop). After this line is printed the dirsrv crashes within seconds. What I also noticed is, that even though it said it freed a lot of pages the retro-changelog does not seem to change in size. The file `/var/lib/dirsrv/slapd-auth-alpha/db/changelog/id2entry.db` is 7.2 G before and after the compacting. Debian 11.4 389-ds-base/stable,now 1.4.4.11-2 amd64 Does someone have an idea how to debug / fix this? Thanks
