[jira] [Updated] (KAFKA-6544) kafka process should exit when it
encounters "java.io.IOException: Too many open files"
[ https://issues.apache.org/jira/browse/KAFKA-6544?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yu Yang updated KAFKA-6544:
---------------------------
Description:
Our kafka cluster encountered a few disk/xfs failures in the cloud vm instances. When a disk/xfs failure happens, kafka process did not exit gracefully. Instead, it ran into "<defunct>" status, with port 9092 still be reachable. when failures like this happens, kafka should shutdown all threads and exit. The following is the kafka logs when the failure happens:
