> Hi, 
> We are seeing a failure on the integrity of our LevelDB datastore which is causing the
broker to stop processing messages.
> We've set up ActiveMQ as a cluster of three nodes (master/slave/slave), each with a local
Zookeeper node, each AMQ/ZK pair sitting on a VMWare host. All based on this guide: http://activemq.apache.org/replicated-leveldb-store.html
> We have 10 Tomcat instances sending messages to the active broker, and 12 Tomcat instances
reading from the VirtualQueue.
> After several hours runtime, we see an exception in the log:
> 2015-12-15 04:03:17,173 | INFO  | Ignoring IO exception, java.io.IOException | org.apache.activemq.util.DefaultIOExceptionHandler
