I don't know about the root cause, but if you're trying to solve the issue,
restarting the controller broker pod should do the trick.

Hi Dhirenda,
Firstly, I am interested in why are you restarting the ZK and Kafka cluster
every night?
Secondly, how are you doing the restarts. For example, in
[Strimzi](https://strimzi.io/), when we roll the Kafka cluster we leave the
designated controller broker until last. For each of the o

Hi Tom,
Doing the nightly restart is the decision of the cluster admin. I have no
control on it.
We have implementation using stateful set. restart is triggered by updating
a annotation in the pod.
Issue is not triggered by kafka cluster restart but the zookeeper servers
restart.
Thanks,
Dhirendra
I suspect this nightly rolling will have something to do with your issues. If
you are just rolling the stateful set in order, with no dependence on
maintaining minISR and other Kafka considerations you are going to hit issues.
If you are running on Kubernetes I would suggest using an Operator li
Hello Kafka users, developers and client-developers,

Hi Tom,
During the rolling restart we check for under replicated partition count to
be zero in the readiness probe before restarting the next POD in order.
This issue never occurred before. It started after we upgraded kafka
version from 2.5.0 to 2.7.1.
So i suspect some bug introduced in the versi
