      Reproduction is fairly easy:

      1. Configure a shared-store master/backup broker pair
      2. Configure clustering with initial-connect-attempts included in the cluster configuration (sample attached)
      3. Start the master and wait for a minute or two
      4. Start the backup

      The master logs the error in the description continuously, even after the backup announces.

    Description

      In a cluster configuration for a single share-store HA pair (needed for backup announcement / failover on shutdown behavior), if initial-connect-attempts is configured on the cluster connection, the following stack is observed continuously at roughly 10-second intervals, even after the backup has entered the cluster and announced:
