The crash looks very much like the one found in https://pagure.io/389-ds-base/issue/48894
it is fixed and the code has also been generally improved with: https://pagure.io/389-ds-base/issue/49401

As far as I can see these patches are not in 1.3.6.1-21, they are in upstream 1.3.6.10.

If you cannot get a version containing these patches, you could try to cleanup the entry state information by export/import reinitialize. It would mean on on server export the data to ldif without replication meta data and reimport it. But this changes the data generation and other replicas have to be reinitialized for replication to work again

I managed to remove the replication conflicts but the orignal issue persist. I found a couple of triggers that crash the directory service, regardless of the freeipa server location. Here are the triggers:
  • Deleting a host that exist in freeipa but no longer exist in our infrastructure
  • Deleting the same host from an hostgroup
  • Re-building the auto membership of the hosts
What worry me the most is that I can't even delete the "dead hosts" from the ldap backend cn=computers OU...it crash the directory service as well.

Attached you'll find the stack trace generated from a core dump.

Please help.

Thanks

I uninstalled "oldipaserver" but I still get the replication conflict.

I try to use ldapdelete but it keep on complaining about the syntax.

Any suggestions?

Thanks,
Alex

sorry, no clue but on
http://www.port389.org/docs/389ds/FAQ/faq.html#debugging-crashes you can
see how to get a core dump file. Inspecting this might help to
understand what is going wrong.
