Hi, I have an ensemble zookeeper consisting of 3 machines and 2 machines with solrcloud.
With a high frequency I see in the logging: *No live SolrServers available to handle this request:[http://solr2:8983/solr/usa_bills_imp_2016_20160623000000_shard1_replica1

question is if it is the maxClauseCount triggering the "No live SolrServers" or if it is something else. I attach the Admin UI of one of the SolrServers. The zookeeper log does not throw any errors regarding to this. Thanks.
