> When adding a looped replication peer (clusterId == peerClusterId), the
> following code terminates the replication source thread, but since the source
> manager still holds a reference, WALs continue to get enqueued, and never get
> cleaned because they're stuck in the queue, leading to an unsustainable
> buildup. Furthermore, the replication statistics thread will continue to
> print statistics for the terminated source.
> {code}
> if (clusterId.equals(peerClusterId) &&
> !replicationEndpoint.canReplicateToSameCluster()) {
> this.terminate("ClusterId " + clusterId + " is replicating to itself:
> peerClusterId "
> + peerClusterId + " which is not allowed by ReplicationEndpoint:"
> + replicationEndpoint.getClass().getName(), null, false);
> }
