Subject no servers hosting shard
Date Tue, 07 Jan 2014 16:57:54 GMT
In our Solr instance we have two shards each running on two servers.  The
server that was the leader for one of the shards ran into a problem, and
when we restarted the service, Solar is no longer electing a leader for the
shard.

The stack traces from the logs are below, and the 'Cloud Dump' from the
Solr console is attached.  We're running Solr 4.4.0.  Any guidance on how
to recover from this?  Restarting or redeploying the service doesn't seem
to make any difference.

Thanks,
Pat.
