Based on my research so far... I am not seeing zookeeper connection issues from zk server side. It seems it is solr side ( zk client) side. This issue is pretty constant now and then. Error 1 Solr: WARN - 2018-02-06 17:35:04.742; org.apache.solr.common.cloud.ConnectionManager; Our previous ZooKeeper session was expired.
