SOLR Cloud 4.6 - PERFORMANCE WARNING: Overlapping onDeckSearchers=2

[Rishi Easwaran]

All,

I am running SOLR Cloud 4.6, everything looks ok, except for this warn message 
constantly in the logs.

Searched around a bit, looks like my solrconfig.xml is configured fine and 
verified there are no explicit commits sent by our clients.

My solrconfig.xml 
 <autoCommit>
            <maxDocs>10000</maxDocs>
            <maxTime>60000</maxTime>
            <openSearcher>false</openSearcher>
        </autoCommit>

       <autoSoftCommit>
         <maxTime>1000</maxTime>
       </autoSoftCommit>


Any idea why its warning every second, the only config that has 1 second is 
softcommit.

Thanks,
Rishi.
