Yet Another SEP11 problem

I wrote last week how my Vista tablet cratered shortly after I installed Symantec Endpoint Protection 11. I’ve rebuilt that computer, and decided not to do any more testing with SEP for a while. If I didn’t have Symantec coming in sometime soon for a NAC demo I’d be evaling McAfee Total Protection Enterprise.
Today I came in after a few days off and found that my desktop is out of hard drive space. After looking around I found 18.6 GB of files in c:\program files\common files\Symantec shared\. Most of these files were in directories named *.tmp. Now I know this sort of thing happened in previous version of Symantec as well, but it hadn’t happened to me. and it hadn’t happened within weeks of installation.
