/**
* MessageCleanupException represents the failure to perform reference counting on messages correctly. This should not
* happen, but there may be programming errors giving race conditions that cause the reference counting to go wrong.
*
* <p/><table id="crc"><caption>CRC Card</caption>
* <tr><th> Responsibilities <th> Collaborations
* <tr><td> Signals that the reference count of a message has gone below zero.
* <tr><td> Indicates that a message store has lost a message which is still referenced.
* </table>
*
* @todo Not an AMQP exception as no status code.
*
* @todo The race conditions leading to this error should be cleaned up, and a runtime exception used instead. If the
* message store loses messages, then something is seriously wrong and it would be sensible to terminate the
* broker. This may be disguising out of memory errors.
