Reset Merge Status after Upgrade to 12.10.11 failed

Hi there, since the upgrade from 12.0.12 to 12.10.11 two weeks ago we see still migration tasks that try to “ResetMergeStatus” and fail.

Systemcheck says that everything is fine and all other things are working. The only thing we changed was that we disabled Prometheus after this upgrade.

Is there a way to dig deeper to find out what in detail fails?

Many thanks
