Description

In some custom environments, the COS cluster synchronization has struggled with many retries and eventually failed after a timeout, usually 60 minutes. It leads to shutdown of DBs in the clusters.

Workaround

There is no workaround, just restart a COS cluster again.

Fix

The bug fix was applied to the cluster synchronization process, which increases self-healing for this synchronization due to communication problems.
