> When a destination is removed, all open file handles inside HashIndex will be
> leaked because HashIndex.clear() closes the index, deletes the backing store
> files, then reopens the files. There is no provision for closing the
> HashIndex without reopening the files. Eventually the broker runs out of
> file handles and hangs.
> For reference, here is the stack trace down to HashIndex.clear from the
> removeDestination call:
