> We have observed that replication source metrics for peer exists on some

> `peerRemoved` workflow which should eventually terminate the source and
> removes the source from the source manager. Now, the problem is
> ReplicationSource thread terminates itself and thus the action to removePeer
> is not complete leaving the metrics there forever for source. This is the
> flow, replication source trying to clean wals
