Dears,

Today morning I changed the log level from DEBUG to INFO in log4j.properties file and did restart nodes one by one.
Now I have problems with my kafka cluster. One node is unstable, Kafka service restarts every few minutes.
I log file there is many lines like this one:

[2024-04-04 08:24:16,019] WARN [Log partition=__consumer_offsets-26, dir=/kafka_data] Non-monotonic update of high watermark from (offset=986277 segment=[986274:554]) to (offset=986274 segment=[986274:0]) (kafka.log.Log)

and:

[2024-04-04 06:47:57,451] ERROR Error while creating ephemeral at /brokers/ids/2, node already exists and owner '216214412779454482' does not match current session '72057609474473995' (kafka.zk.KafkaZkClient$CheckedEphemeral)

How to solve this problem?

Best regards,
Dan
