Description

When shutting down a single node within a cluster, then ERROR messages are emitted on the logs of the remaining nodes. Take a look at this project which provides a minimal working example (MWE) and documents the steps to reproduce. All versions involved are documented in code as well.

Contributor guide

Research direction
Reproduce the issue using the provided MWE. Then trace the AssociationError in the logs to determine why it is emitted during coordinated shutdown. Investigate the cluster shutdown sequence and identify if the error is spurious or indicates a real problem.
