> Thanks to [~mewmewball] for catching this one.
> Accidentally executing the same instance of Solr twice causes the second start instance to die with an "Address already in use", but not before deleting the first instance's live_node entry, emitting "Found a previous node that still exists while trying to register a new live node <node> - removing existing node to create another".
> The second start instance dies and its ephemeral node is then removed, causing /live_nodes/<node> to be empty since the first start instance's live_node was deleted by the second.
