BTW. worker server has no any zookeeper session expired log and run with no any issues at the same time.

For each expired session, the log behavor: 1. close socket and reconnect [WARN] 2020-06-18 02:20:34.110 org.apache.zookeeper.ClientCnxn:[1108] - Client session timed out, have not heard from server in 61353ms for sessionid...

here is my zookeeper settting: #dolphinscheduler failover directory zookeeper.session.timeout=60000 zookeeper.connection.timeout=60000 zookeeper.retry.base.sleep=2000 zookeeper.retry.max.sleep=120000 zookeeper.retry.maxtime=29
