# Problem description Spring Kafka SSL producers are throwing timeouts when producing to a Kafka cluster with 3 brokers. I set up the cluster on Kubernetes according to [https://github.com/Yolean/kubernetes-kafka] , altering only the broker config and services to arrange outside access. Some observations: - The SSL configuration seems correct, since messages are sent and received for large periods of time (e.g. hours) before showing intermittent problems. - Both the server and clients have plenty of resources left. - The network is stable and powerful enough (200 mbit, no downtime in the last year). - The errors do not appear in a PLAINTEXT setup. - Configurations for the three brokers are identical apart from their broker ID and listeners. - No errors appear in the broker log or Spring Kafka consumers. `2018-06-06 11:15:44.103 ERROR 1 --- [ad | producer-1] o.s.k.support.LoggingProducerListener : Exception thrown when sending a message with key='null' and payload='[...redacted...]': org.apache.kafka.common.errors.TimeoutException: Expiring 1 record(s) for topicname-0: 30001 ms has passed since last append` # Detailed description https://stackoverflow.com/questions/50725643/spring-kafka-producers-throwing-timeoutexceptions # Question How can I find the cause of this problem? -- This message was sent by Atlassian JIRA (v7.6.3#76005)
