Answer 1

I had the same issue. I ended up solving it by terminating all kafka clients i had. Not only containers but an UI as well. I was using Conduktor.

Answer 2

Try restarting the client service. I hit the same issue and was able to resolve by restarting my docker container that was trying to connect to zookeeper.

The reason for this error is that your client is trying to connect with the transaction id it stored from the previous zookeeper session and when zookeeper goes down and comes back up it starts from a lower transaction id.
