    Description

      Zookeeper connection timeout is experienced, with all 3 zookeeper. Apache Solr is removed from the live nodes once the connection timesout and connection re-establishes after restarting the Solr service. Same issue observed with different node where almost everyday a Solr node faces this connection timeout.

      Solr version - 8.6.0
