@ Pete: Upgrading is out of the question for our organization. The Symantec Engineers we work with on a regular basis recommend upgrading, but we have so many issues with the current RU7 MP1 that upgrading will only compound these issues, or create new ones. I saw the link that you posted, but now matter how many times I empty it, (a) the directory still populates (b) it cannot delete the 100MB+ file. See below response to Rafeeq.
@ Rafeeq: I delete these temp files, but then they appear. If I don't delete these temp files, then they stay in the folder and don't disappear on their own as they are supposed to. What is WORSE: I am unable to delete the tmp file that is over 100 MB
