It is also possible that an unclean shutdown or similar leaves orphaned defer files around because the deletion never completes. Or that someone manually deleted a queue file without deleting the corresponding "defer" file. When using "long queue ids" it is safe to delete sufficiently old deferred files by hand, if the corresponding queue files are no longer around. This was discussed in a recent thread this year... -- Viktor.
