To add to what Emile already said: RabbitMQ prior to 2.8.0 did not force 
an fsync on declare / delete operations for durable objects, so it was 
possible for such operations to get (effectively) rolled back after a 
crash. I don't know how long you can manage to go without an fsync 
though - I would expect you'd struggle to get to an hour and it sounds 
like your definitions were much older than that.

However, an upgrade is, as usual, recommended :-)

Cheers, Simon
