> When broker runs out of disk space, the journal excepts and the send fails with an exception as expected. The default IO exception handler ignores the exception. (aside: it is possible to install an exception handler that shuts down the broker: http://activemq.apache.org/configurable-ioexception-handling.html)
> On restart, the last journal file that failed a write is left with 0 size, this impedes restart recovery as it cannot be parsed.
> {code}ERROR | Failed to start ActiveMQ JMS Message Broker. Reason: java.io.EOFException
> java.io.EOFException
