Hi Ondřej,
Which parts of the config would be good to see (sending over the contents of all the ldif files in slapd.d seems like overkill to send to the list)?
Hi Ben, a list of overlays (the dns of the database's cn=config subtree) plus the sanitised contents of syncprov and syncrepl config should be enough.
Replication appears to have been stable for the past several days, but I do continue to see repeated instances of logs (on the consumer) like this, even when replication seems to be working (verified both by watching contextCSN values on producer and consumer, as well as by making changes to entries on the primary provider and seeing those changes replicated in the consumer):
Could you provide a little more context from the log? In particular, is the entry being modified locally at the same time? When syncrepl tries to update an entry, it now attaches an assert control ensuring the entry still carries the entryCSN it did as it was trying to figure out what changes were needed. If that failed, it's because **something** updated the entry before syncrepl's change managed to land there and the assert control didn't match anymore.
And (but there isn't sufficient information in the logs) the retried modification (rereading the entry and checking what to do) probably succeeded. If you temporarily enable accesslog on the database and record both successful and failed operations, we might be able to see what happened in detail.
