Jan Høydahl closed SOLR-5724.
-----------------------------
    Resolution: Incomplete

Closing this issue as "Incomplete", as this is not the right channel to report general production problems, and there is not enough information provided to say that it is a bug.

Please start a mail thread on the solr-user mailing list and provide more detailed information about your setup, OS, memory, network details, configuration, logs etc, and then if we later believe this is due to a new bug, we'll open a more targeted JIRA.

> One server is stuck in state "recovering" while the other is stuck in state "down". After waiting 45 minutes or so for the cluster to recover, the statuses were the same. 
> Log messages on the "recovering" server: (Just the individual errors for brevity, I can provide full stack traces if that is helpful)

> We are not the leader
> ClusterState says we are the leader, but locally we don't think so
> cancelElection did not find election node to remove
> We are not the leader
> No registered leader was found, collection:listsC slice:shard1
