Sounds like a SpringBoot issue rather than a KS issues.

Hi, My SpringBoot stream application works fine in a fresh start of the clustered environment. But when I restart one of the pods out of two pods, I start getting the below exception from "KafkaStreams.store". I debugged the state but found it was RUNNING. *org.apache.kafka.streams.errors.InvalidStateStoreException: The state store, wkstore, may have migrated to another instance. * *at org.apache.kafka.streams.state.internals.WrappingStoreProvider.stores(WrappingStoreProvider.java:67) * *at org.apache.kafka.streams.state.internals.CompositeReadOnlyWindowStore.fetchAll(CompositeReadOnlyWindowStore.java:175)* To fix this, I must restart all the pods/instances or the cluster. *Steps to reproduce* 1. Kafka Stream application environment 'kafka-streams', version: '3.0.1' 'kafka-clients', version: '3.0.1' 2. Create a cluster environment with at least two replication factors of the Kafka Stream application. 3. Restart one of the pods. 4. Call KafkaStreams:store(), it starts throwing an exception. If not then try at least 5 times to restart the same pod. Priority: *Blocker* *Regards,* Nawal Sah (M): +91-9717932863
