Hello All,
Running OpenLDAP version 2.4.58 on Ubuntu 20.04 in multicaster mode.
Under normal conditions, all operations perform normally in terms of
replication consistency. However, when performing a stream of "ADD"
operations eventually producer/consumer go out of sync where consumer
thinks it has latest state than producer. All the write operations
including ADD are pointed to a producer node (not load balancing the
writes). Introduced 30 second delay to "ADD" operations (for the sake
of testing) and experiencing the same behavior. The issue is manifesting
after adding around 4k entries (sometimes even sooner).
I would note that OpenLDAP 2.4 series is no longer supported and that the
OpenLDAP 2.5 series has numerous replication related changes. I'd strongly
advise deploying OpenLDAP 2.5 and seeing if this resolves the issue.
If you are unable to package OpenLDAP 2.5 yourself, you may want to use the
freely available from Symas or the LTB project.
