Please report such incidents in as much detail as you can. The whole
point of "store and forward" is to prevent that. Runners should not
alter the queuefile until they're done. If they crash in the middle,
they should leave the queuefile they received and maybe a work file.
The actual process of picking up a queue entry[1] atomically renames the
queue file from .pck to .bak so until the runner finishes processing the
file and removes the .bak, there is always a .pck or .bak file in the
queue. If the runner dies for any reason in processing, whether because
of a crash or external event, upon restart it will process the .bak
file(s) so messages are never lost for this reason.
