Curious. So one plausible sequence of events is this:

1. queue gets deleted
2. rabbit attempts a recursive queue deletion by...
2.1 getting the dir listing
2.2 deleting all the files
2.3 deleting the dir - bang! the dir still has files in it
3. some time later the remaining file(s) in the dir vanish

I wonder whether there is some peculiar filesystem issue here. Noting 
the /mnt prefix, are these dirs nfs mounted or on some other sort of 
network storage?


To get you going again, it may be sufficient to delete the dir manually; 
you might then be able to re-declare a queue with the same name.

But given that the fault occurred before, it's likely going to occur again.
