Hi,
(( This was also reported as an issue at github [1], but there isn't much activity
there. ))
Each day there several messages with "WARN - content-sync-plugin -
sync_update_persist_betxn_pre_op ...". It is unclear why they show up.
Briefly about the setup.
This is in a IPA deployment. We have three masters/replicas in a triangular topology, A-B, B-C, C-A.
The systems are called: rotte, linge and iparep4.
rotte is CentOS 7, with 389-ds-base-1.3.9.1-13.el7_7.x86_64
linge and iparep4 are CentOS 8 Stream, with 389-ds-base-1.4.3.23-2.module_el8.5.0+835+5d54734c.x86_64
The messages seem to have a relation to DNS updates triggered by a DHCP server. These
updates come in on rotte, the CentOS7 system. Next, they get replicated to the two CentOS
systems.
At least a few times per day, on the two CentOS system I see the following. Even though
they are just(?) warnings, I still don't like it.
