My strimzi-topic-operator pod is unavailable and the only error I am able to see in my logs is the same Thread blocked
error that is already mentioned in this issue. I am using strimzi 0.8.2
If you need more information please let me know what you need.
@chris922 Could you please share your log as well?
Yes for sure, the stacktrace itself and even the threadname is the same.
Unfortunately my TO pod will not start and this exception is the only one that I am able to see in the logs. It will be logged every second.

Judging from the Zookeeper address, you installed the standalone version of the Topic Operator (i.e. kubectl apply -f install/topic-operator
or something similar).
How did you deployed the Kafka cluster? The standalone version of the Topic Operator is supposed to be used if you have your own version of Kafka. When you use Strimzi to deploy Kafka as well, you should deploy the Topic Operator as part of the cluster. To do that, you have to use the following in the custom resource configuring Kafka:
apiVersion: kafka.strimzi.io/v1alpha1
kind: Kafka
metadata:
name: my-cluster
spec:
kafka:
# ...
zookeeper:
# ...
entityOperator:
topicOperator: {}
userOperator: {}
With that, the Topic Operator will be deployed together with Kafka and automatically setup things like TLS authentication between the Topic Operator and Zookeeper and Kafka etc. These things are probably why it doesn't work for you right now.
I installed Kafka using the cluster operator from strimzi, so it should be exactly the way you described. The cluster operator deployed then the required pods, e. g. kafka and zookeeper. This worked out really well, also the KafkaConnect resource was deployed and is accessible. Everything in the same namespace.
My k8s cluster in general is installed on VMs using Rancher 2.1.1.
In my Kafka cluster configuration I also have this configuration, maybe it's relevant as you mentioned TLS:
listeners:
plain: {}
tls: {}
The configuration I used to deploy everything is nearly the same like provided in the strimzi download (in general I just changed names). I used the getting-started guide in the strimzi documentation.
I noticed that I can change the strimzi loglevel, I set it to TRACE. As it might be helpful here is an extract, starting with opening the connection and ending with the exception.
