Ouch. Stuff like that is why making sure program output goes to /var or other local file system is usually a good thing. I seem to remember us getting bit by a similar misbehavior in TSM, but I don't know the details because I was busier with GPFS and LTFS/EE than TSM. Though I have to wonder how TSM could be a decades-old product and still have misbehaviors in basic things like failed reads on input prompts...
