> There are already issues reporting this in AMQ-3098 and AMQ-5786 but they have been closed as Incomplete, I've left a comment on 5786 but I fear that it may get lost.
> Fundamentally KahaDB & ActiveMQ do not survive if Queues start filling up and buffering to KahaDB disk when the disk then becomes full because of an external issue (in our case rsyslog).
> Because KahaDB does not pre-allocate space, it seems vunerable to this case.
> I will attach broker logs and Kahadb store during the corrupted state.
