[jira] [Created] (RATIS-2083) Timer thread leak when log level is DEBUG

Sammi Chen created RATIS-2083:
---------------------------------

             Summary: Timer thread leak when log level is DEBUG
                 Key: RATIS-2083
                 URL: https://issues.apache.org/jira/browse/RATIS-2083
             Project: Ratis
          Issue Type: Bug
            Reporter: Sammi Chen
            Assignee: Sammi Chen


During a DN issue investigation, it's found that there are thousands of Timer threads in the jstack output. A further investigation shows that Ratis creates new Timer() in every SlidingWindow#RequestMap object when log level is debug.  See the attached jstack file.
