Summary: "java.lang.AssertionError: Memory was freed" exception in CompactionExecutor Key: CASSANDRA-8210 URL: https://issues.apache.org/jira/browse/CASSANDRA-8210 Project: Cassandra Issue Type: Bug Components: Core Environment: DSE 4.5.2, Cassandra 2.0.10, OEL 6.5, kernel 3.8.13-44.el6uek.x86_64, 128Gb of RAM, swap disabled, JRE 1.7.0_67-b01 Reporter: Nikolai Grigoriev Priority: Minor I have just got this problem on multiple nodes. Cassandra 2.0.10 (DSE 4.5.2). After looking through the history I have found that it was actually happening on all nodes since the start of large compaction process (I've loaded tons of data in the system and then turned off all load to let it compact the data). {code} ERROR [CompactionExecutor:1196] 2014-10-28 17:14:50,124 CassandraDaemon.java (line 199) Exception in thread Thread[CompactionExecutor:1196,1,main] java.lang.AssertionError: Memory was freed at org.apache.cassandra.io.util.Memory.checkPosition(Memory.java:259) at org.apache.cassandra.io.util.Memory.getInt(Memory.java:211) at org.apache.cassandra.io.sstable.IndexSummary.getIndex(IndexSummary.java:79) at org.apache.cassandra.io.sstable.IndexSummary.getKey(IndexSummary.java:84) at org.apache.cassandra.io.sstable.IndexSummary.binarySearch(IndexSummary.java:58) at org.apache.cassandra.io.sstable.SSTableReader.getSampleIndexesForRanges(SSTableReader.java:692) at org.apache.cassandra.io.sstable.SSTableReader.estimatedKeysForRanges(SSTableReader.java:663) at org.apache.cassandra.db.compaction.AbstractCompactionStrategy.worthDroppingTombstones(AbstractCompactionStrategy.java:328) at org.apache.cassandra.db.compaction.LeveledCompactionStrategy.findDroppableSSTable(LeveledCompactionStrategy.java:354) at org.apache.cassandra.db.compaction.LeveledCompactionStrategy.getMaximalTask(LeveledCompactionStrategy.java:125) at org.apache.cassandra.db.compaction.LeveledCompactionStrategy.getNextBackgroundTask(LeveledCompactionStrategy.java:113) at org.apache.cassandra.db.compaction.CompactionManager$BackgroundCompactionTask.run(CompactionManager.java:192) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745) {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
