(moderation:
One of my computers keeps failing to finish a work unit. Here is the error message. Can you help me figure out why?

Looks like "graphics bug" symptoms. (I presume you are using the BOINC screensaver or "Show graphics" option.) The "graphics bug" is a problem with the Einstein app (v4.79) and it is likely to occur with any BOINC version later than v4.19. You have two choices: 1/ quit using graphics (screensaver or "Show graphics" option); or, try the Beta app. (I recommend the Beta app). You can find the Beta app link under More Information on the E@H home page.

Doc,
That particular errorcode is a symptom of incompatibility between the v4.79 Einstein app and newer Boinc clients. It usually surfaces when displaying the Einstein graphics/screensaver. If your Celeron box is set to run the Einstein screensaver when idle, you'll get errored-out WUs. The fix is to either disable the screensaver and never click on "Show Graphics" or (recommended) upgrade to the Einstein 0.18 beta app, available under "more information" on the Einstein homepage. The beta is very stable and has been tested now for over 3 months.
Regards,
Michael
