Kafka clients are getting disconnected frequently

Hello Strimizi Users,

We have deployed kafka using strmizi operator v0.20.1 and we see the kafka clients are getting disconnected frequently, though we don't see any stability issues in the applications using kafka.

We see the same behaviour in the other environments where we have deployed kafka using the strimzi operator v0.20.0

We don't see this issue for the environments that does not uses kafka deployed using strimizi operator.

The following is our application logs, If you see there are continuous connection failures.
