Subject [jira] [Created] (CASSANDRA-13906) Properly close StreamCompressionInputStream to release any ByteBuf
Date Tue, 26 Sep 2017 23:39:00 GMT
Jason Brown created CASSANDRA-13906:
---------------------------------------

             Summary: Properly close StreamCompressionInputStream to release any ByteBuf
                 Key: CASSANDRA-13906
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-13906
             Project: Cassandra
          Issue Type: Bug
            Reporter: Jason Brown
            Assignee: Jason Brown


When running dtests for trunk (4.x) that perform some streaming, sometimes a {{ByteBuf}} is
not released properly, and we get this error in the logs (causing the dtest to fail):

{code}
ERROR [MessagingService-NettyOutbound-Thread-4-2] 2017-09-26 13:42:37,940 Slf4JLogger.java:176
- LEAK: ByteBuf.release() was not called before it's garbage-collected. Enable advanced leak
reporting to find out where the leak occurred. To enable advanced leak reporting, specify
the JVM option '-Dio.netty.leakDetection.level=advanced' or call ResourceLeakDetector.setLevel()
See http://netty.io/wiki/reference-counted-objects.html for more information.
