A situation that happens if the folder is of type "mbox", is that procmail is adding a new email at the end, while the MUA is removing another one from the middle. Even worse, the MUA could be compacting the folder. The way to avoid this is using a locking mechanism, but each program uses a diferent method, and procmail can be told about it - except that diferent MUAs use diferent locks :-(
Of course, using maildir folders the problem is not so bad.
