             Summary: long-test MeteredFlusherTest fails with heap OOM
                 Key: CASSANDRA-8631
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8631
             Project: Cassandra
          Issue Type: Test
         Environment: cassandra-2.0 commit 90780b5
            Reporter: Michael Shuler
            Priority: Minor


I attempted to find a spot where this test actually passes, and I was unable to do so. I tried back to 1.1 HEAD and various release tags under jdk7 and jdk6 for <= 1.2 tags. In 1.2.0 with jdk6, the test times out with java.lang.OutOfMemoryError: GC overhead limit exceeded, so it's similar.
