Hi everyone, I've got an error "java.io.IOException: Too many open files" on usage EmbeddedKafkaCluster with scenarios when a several dozen topics are created and deleted. Examination of open descriptors with `lsof` showed that after stopping the test cluster (EmbeddedKafkaCluster), there are open files of deleted topics. Please take a look at the PR #13173 with demo. (See [1])
My question: Is this behavior expected for a test cluster? The PR contains an ugly hotfix to the problem described. With no desire to merge as is. Just for demo. I guess the correct fix should be more accurate. [1]. https://github.com/apache/kafka/pull/13173 -- With best regards, Taras Ledkov
