> CassandraDaemon - recent unsafe memory access operation in compiled Java code
> -----------------------------------------------------------------------------
>
> Key: CASSANDRA-5737
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5737
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.2.6
> Environment: Amazon EC2, XLarge instance.
> Ubuntu 12.04.2 LTS
> Raid 0 disks, with ext4
> Reporter: Glyn Davies
>
> I'm using 1.2.6 on Ubuntu AWS m1.xlarge instances with the Datastax Community package and have tried using Java versions jdk1.7.0_25 jre1.6.0_45
> Also testing with and without libjna-java (ie the JNA jar)
> However, something has triggered a bug in the CassandraDaemon:
> ERROR [COMMIT-LOG-ALLOCATOR] 2013-07-05 15:00:51,663 CassandraDaemon.java (line 192) Exception in thread Thread[COMMIT-LOG-ALLOCATOR,5,main]
> java.lang.InternalError: a fault occurred in a recent unsafe memory access operation in compiled Java code
> at org.apache.cassandra.db.commitlog.CommitLogSegment.<init>(CommitLogSegment.java:126)
> at org.apache.cassandra.db.commitlog.CommitLogSegment.freshSegment(CommitLogSegment.java:81)
> at org.apache.cassandra.db.commitlog.CommitLogAllocator.createFreshSegment(CommitLogAllocator.java:250)

> This brought two nodes down out of a three node cluster – using QUORUM write with 3 replicas.
> Restarting the node replays this error, so I have the system in a 'stable' unstable state – which is probably a good place for trouble shooting.
> Presumably something a client wrote triggered this situation, and the other third node was to be the final replication point – and is thus still up.
> Subsequently discovered that only a reboot will allow that node to come back up.
> Java Bug raised with Oracle after finding a Java dump text indicating a SIGBUS.

> At this point, I'm thinking that there is potentially a Linux kernel bug being triggered?
