AWS Kafka not working after security patches -

Hi

AWS Kafka not working after security patches - 

The problem is rare, but it is a major one.

There is a problem with the producer pushing into MSK. This results in data loss. After automatic security patches we faced this problem and for hot fixes we needed to switch the broker nodes with new ones.

Please Help me out in this.

Attaching the logs which i getting.

Current configuration:-

2 availability zone

1 broker in each AZ. 

Type - kafka.t3.small (taking this as we have less usage)
