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

rajinisivaram opened a new pull request #5805: KAFKA-7513: Fix timing issue in SaslAuthenticatorFailureDelayTest
URL: https://github.com/apache/kafka/pull/5805
 
 
   Reduce tick interval of the mock timer and avoid large timer increments to avoid hitting idle expiry on the client-side before delayed close is processed by the server. Also reduce poll interval in the server to make the test complete faster (since delayed close is only processed when poll returns).
