Have smaller server identifier, so dropping the connection
Is this issue got fixed in 3.4.13 ? i thought it got fixed but i am still
seeing this when leader nodes is with lower myid and reboot a follower with
higher myid.
Have smaller server identifier, so dropping the connection: (3, 2)
Thanks,
Ram

Hi Ram,
I might be missing something from your explanation, but that error message alone is not an issue. All ZK nodes open connection to each other, but having 2 connections between the same nodes is redundant and one of them has to be closed. To decide which one to close ZK use the server identifiers: node with smaller id closes the initiated connection. That’s the rule and decision is shown in the logs.
