[jira] [Created] (KAFKA-5872) Transient failure in SslSelectorTest.testMuteOnOOM

-------------------------------------

             Summary: Transient failure in SslSelectorTest.testMuteOnOOM
                 Key: KAFKA-5872
                 URL: https://issues.apache.org/jira/browse/KAFKA-5872
             Project: Kafka
          Issue Type: Bug
          Components: network
            Reporter: Rajini Sivaram
            Assignee: Rajini Sivaram
             Fix For: 1.0.0


There are a couple of issues:
1. `Selector.determineHandlingOrder()` currently doesn't clear selection keys when keys are shuffled. This can result in select returning zero even when there are ready keys, resulting in a tight loop of polls with no keys processed.
2. The test expects `Selector.isOutOfMemory()` to be set in a poll that waits only for 10ms. This is expecting two reads from two connections to be processed within 10ms of each other, which may not always be the case.
