-----------------------------------------
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.
