Kafka controller logs shows a leader imbalance as 1 and the elections are keep on happening every 5 minutes

Question

The following error appears in the logs every 5 minutes from feb 15 , and it seems like the leader election is occurring at this interval for some reason. Is this something to be concerned about? Should I open a support case, or is this behavior normal? Could you please clarify?
