-------------------------------

             Summary: LevelDB IOException
                 Key: AMQ-6415
                 URL: https://issues.apache.org/jira/browse/AMQ-6415
             Project: ActiveMQ
          Issue Type: Bug
          Components: Message Store
    Affects Versions: 5.14.0
         Environment: Ubuntu 14.04, 32bit, OpenJDK 7u111
            Reporter: John Leach


two brokers bridged together, producers and consumers spread across the two.

After about 8 hours or so processing ~30 messages/second, amq logs a java.io.IOException, shuts down, and is restarted where it seems to continue on its way:

We'd been running 5.9.1 on these exact same servers for many months using leveldb without this problem. Upgraded to 5.14.0 yesterday and hit it twice already. I tried wiping out the leveldb database before starting as a test and it still reoccurred.

Interesting thing is, it happened on both servers within a couple minutes of each other, even though they had quite different uptimes.
