It's possible you got some WUs like that. Here is what you can do. 1. Open the Boinc Manager 2. View Menu and make sure you're using advanced mode 3. Go to the 'tasks' tab 4. If you want, select all WUs which are NOT application '(321) LLR' 5. Abort those WUs 6. At this point, you should be processing 321 WUs exclusively Hope this helps.
