Resolution: Cannot Reproduce
Fix Version/s: None
debian jesse latest release, updated Feb. 20th
When launching Cassandra 3.0.3, with java version "1.8.0_74", Cassandra writes the following to the debug file before a segmentation fault occurs bringing down the JVM - the problem is repeatable.
DEBUG [CompactionExecutor:1] 2016-02-20 18:26:16,892 CompactionTask.java:146 - Compacting (56f677c0-d829-11e5-b23a-25dbd4d727f6) [/var/lib/cassandra/data/sensordb/periodicReading/ma-367-big-Data.db:level=0, /var/lib/cassandra/data/sensordb/periodicReading/ma-368-big-Data.db:level=0, /var/lib/cassandra/data/sensordb/periodicReading/ma-371-big-Data.db:level=0, /var/lib/cassandra/data/sensordb/periodicReading/ma-370-big-Data.db:level=0, /var/lib/cassandra/data/sensordb/periodicReading/ma-369-big-Data.db:level=0, ]
The JVM error that occurs is the following:
# A fatal error has been detected by the Java Runtime Environment:

Even if all of the files associated with "ma-[NNN]" are removed, the JVM dies with the same error after the next group of "ma-[NNN]" are eventually written out and compacted.
Though this may be strictly a JVM problem, I have seen the issue in Oracle JVM 8.0_65 and 8.0_74 and I raise it in case this problem is due to JNI usage of an external compression library or some direct memory usage.
I have a core dump if that is helpful to anyone.
CASSANDRA-11201 may also be related although when the exception referenced in the bug occurs, the JVM remains alive.
