Well, the amount of problems being reported might be higher for 2.4. But
this does not say anything about stability of your particular
configuration. One of the reasons for more issues being reported for 2.4
probably is that many deployments were already migrated to 2.4. So
naturally if less people are using 2.3 there will be less issues reported.

I would say I consider current 2.4.15 more stable than 2.3.43 when using the same feature set. In particular because of numerous fixes for issues that are currently found in 2.3.43. I of course have no idea whether or not any of those fixes addresses your particular issue. I haven't seen this, and all my installs use delta-syncrepl. I'm wondering if it could be related however to ITS#5985. How many replicas do you have total? If there are ones in particular that fall way behind, do they end up falling back into full refresh mode?

I have a total of ten replica systems. All ten will wind up missing the same updates. They don't realize that they have missed them. Their contextcsn syncs up with the one on the master server.

I believe the changes are not being placed in the delta database (cn=accesslog).

I'll be sure to check the accesslog database the next time the replicas miss changes and see if those changes are listed there or not.
