Rocco Varela created CASSANDRA-9213:

             Summary: Compaction errors observed during heavy write load: BAD RELEASE
                 Key: CASSANDRA-9213
             Project: Cassandra
          Issue Type: Bug
         Environment: Cassandra
Ubuntu 14.04.2
java version "1.7.0_45"
10-node cluster, RF = 3
            Reporter: Rocco Varela
            Assignee: Benedict
             Fix For: 2.1.4
         Attachments: COMPACTION-ERR.log

During heavy write load testing we're seeing occasional compaction errors with  the following
error message:

ERROR [CompactionExecutor:40] 2015-04-16 17:01:16,936 - BAD RELEASE: attempted
to release a reference (org.apache.cassandra.utils.concurrent.Ref$State@        31d969bd)
that has already been released
ERROR [CompactionExecutor:40] 2015-04-16 17:01:22,190 - Exception
in thread Thread[CompactionExecutor:40,1,main]
java.lang.AssertionError: null
 at ~[cassandra-all-]
 at org.apache.cassandra.db.DataTracker.unmarkCompacting( ~[cassandra-all-]

I have turned on debugrefcount in bin/cassandra:launch_service() and I will repost another
stack trace when it happens again.

cassandra_parms="$cassandra_parms -Dcassandra.debugrefcount=true"
