Critical If the broker encounters an IOException from the persistence store, it correctly shuts down.
However the mq-fabric bundle is supposed to attempt to restart the broker thereafter.
This is not happening in this particular case.
Relevant broker log contains:

But there is no further logging afterwards. No attempts to restart the broker.
