Hi All, I am getting schemaregistry crashloopbackoff. When I check the logs there is SchemaRegistryInitializationException: Error initializing kafka store while initializing schema registry. Please find the logs below: ERROR Error starting the schema registry (io.confluent.kafka.schemaregistry.rest.SchemaRegistryRestApplication) io.confluent.kafka.schemaregistry.exceptions.SchemaRegistryInitializationException: Error initializing kafka store while initializing schema registry at io.confluent.kafka.schemaregistry.storage.KafkaSchemaRegistry.init(KafkaSchemaRegistry.java:321) at io.confluent.kafka.schemaregistry.rest.SchemaRegistryRestApplication.initSchemaRegistry(SchemaRegistryRestApplication.java:75) at io.confluent.kafka.schemaregistry.rest.SchemaRegistryRestApplication.configureBaseApplication(SchemaRegistryRestApplication.java:90) at io.confluent.rest.Application.configureHandler(Application.java:285) at io.confluent.rest.ApplicationServer.doStart(ApplicationServer.java:270) at org.eclipse.jetty.util.component.AbstractLifeCycle.start(AbstractLifeCycle.java:73) at io.confluent.kafka.schemaregistry.rest.SchemaRegistryMain.main(SchemaRegistryMain.java:44) Caused by: io.confluent.kafka.schemaregistry.storage.exceptions.StoreInitializationException: io.confluent.kafka.schemaregistry.storage.exceptions.StoreTimeoutException: KafkaStoreReaderThread failed to reach target offset within the timeout interval. targetOffset: 2326437, offsetReached: 2260035, timeout(ms): 60000 at io.confluent.kafka.schemaregistry.storage.KafkaStore.init(KafkaStore.java:151) at io.confluent.kafka.schemaregistry.storage.KafkaSchemaRegistry.init(KafkaSchemaRegistry.java:319) ... 6 more Caused by: io.confluent.kafka.schemaregistry.storage.exceptions.StoreTimeoutException: KafkaStoreReaderThread failed to reach target offset within the timeout interval. targetOffset: 2326437, offsetReached: 2260035, timeout(ms): 60000 at io.confluent.kafka.schemaregistry.storage.KafkaStoreReaderThread.waitUntilOffset(KafkaStoreReaderThread.java:369) at io.confluent.kafka.schemaregistry.storage.KafkaStore.waitUntilKafkaReaderReachesOffset(KafkaStore.java:317) at io.confluent.kafka.schemaregistry.storage.KafkaStore.waitUntilKafkaReaderReachesLastOffset(KafkaStore.java:297) at io.confluent.kafka.schemaregistry.storage.KafkaStore.init(KafkaStore.java:149) ... 7 more I have checked the kafka and zookeeper pods there is no failure and the pods are in ready state. Can anyone please suggest me why schemaregistry pod is failing here. Thanks

As per error message, you can try increasing kafkastore.init.timeout.ms. Maybe you have too many schemas, or schemas are too big and SchemaRegistry doesn't manage to process all of them in time.
