Seeing EOF/panic with v1.42.1 against MSK (Amazon) 2.4.1.1 that is not seen in v1.42.0

[JeffBNimble]

Is anyone having trouble with the latest v1.42.1 release? I pulled it in and now my service panics with either a "broken pipe" error or an EOF error when attempting to consume. I reverted back to 1.42.0 and everything works fine.

@JeffBNimble can you add logs from Sarama and/or Kafka to help show your problem? You can set sarama.Logger to a log.Logger to capture Sarama debug output.

Can you also double check and confirm that your apps sarama.Config has sarama.Config{Version: sarama.V2_4_1_1} or lower set?

My assumption is that #2705 is causing the problem and your remote server doesn't understand the protocol version it is receiving, but if your sarama.Config version matches your remote cluster then it shouldn't be happening

Hello @dnwe. I'm incredibly sorry for the delay in responding. I saw your response a few weeks ago and have been at an AWS conference and then I'm on PTO through the end of the year. I will verify this in early January when I return and will reply. Thank you for checking back on this.
