Hello list,
I am trying to setup referral chaining in a multi-master setup. I can
setup chaining to one of the masters without any problems. And I can
perform a MOD operation that is then referral chased and performed on
the
master.
OpenLDAP 2.4.31 is extremely old. The current release is 2.4.39. You
should attempt to reproduce this with the current RE24 code, which as
numerous fixes even since 2.4.39, as we are preparing for 2.4.40. If
you can still reproduce this with the current RE24 code, then please
file a bug report at http://www.openldap.org/its/
Thanks!

Just managed to reproduce the bug on RE24 (commit
#dbc6741750de79b852ec9f728abb8b1425b6f03f). Exact same setup as
described earlier with the same result: replica crashes on a MOD operation.
I'm still not sure if this is a bug or a misconfiguration on my part.
Attached is the crash log with loglevel set to "stats trace args sync"
(again with no indication of any errors).
Thanks,
