Hello,
Currently Zookeeper and kafka do not work appropriately and the logs are not streaming to logstash. The var-log partitions across the zookeeper cluster are filled up to 100 percent. We are getting the following messages when we investigated the logs and the services status: 1 . Zookeeper logs 2018-01-03 06:16:55,001 [myid:1] - WARN [SendWorker:2:QuorumCnxManager$SendWorker@736] - Send worker leaving thread 2018-01-03 06:23:08,943 [myid:1] - WARN [RecvWorker:3:QuorumCnxManager$RecvWorker@810] - Connection broken for id 3, my id = 1, error = java.io.EOFException at java.io.DataInputStream.readInt(DataInputStream.java:392) at org.apache.zookeeper.server.quorum.QuorumCnxManager$RecvWorker.run(QuorumCnxManager.java:795) 2018-01-03 06:23:08,943 [myid:1] - WARN [RecvWorker:3:QuorumCnxManager$RecvWorker@813] - Interrupting SendWorker 2018-01-03 06:23:08,943 [myid:1] - WARN [QuorumPeer[myid=1]/0.0.0.0:2181 :Follower@87] - Exception when following the leader java.io.EOFException at java.io.DataInputStream.readInt(DataInputStream.java:392) at org.apache. **Consumer check output kafka-console-consumer --bootstrap-server localhost:2181 --topic RCCSWA_DHCP_1 --from-beginning [2018-01-03 07:39:27,559] WARN Bootstrap broker localhost:2181 disconnected (org.apache.kafka.clients.NetworkClient) [2018-01-03 07:39:27,660] WARN Bootstrap broker localhost:2181 disconnected (org.apache.kafka.clients.NetworkClient) [2018-01-03 07:39:27,761] WARN Bootstrap broker localhost:2181 disconnected (org.apache.kafka.clients.NetworkClient) 2.
