Can someone venture a guess as to what wrong on this computer?

It appears that SETI issued over 1000 tasks in 37 hours to this one computer unless I am interpreting something incorrectly. Always a strong possibility :).

It may look as if he has over 1,000 tasks in progress, but will only have those v8.03 tasks really on the system. Everyone with a Mac of sorts had the problem yesterday where Eric rereleased a science application version without actually building it.

He changed a configuration file on the server and thought that would be fixing the problem that had happened first. But this fix made people with Macs be sent v8.02 work while they only had a v8.01 application. So all work coming in was discarded by BOINC because the work mismatched the application they had. The only available application for download was also v8.01, so even a project reset didn't fix that problem.

Trouble is also, when BOINC discards the work, it does not tell the server that it did. Now, as to why exactly that 8 core system + GPU has 1,000 tasks I don't know. I do know though that the actual in progress are only the v8.03 tasks he has.

That'll be because the "maximum tasks in progress" check is only done for tasks reported as present by the client. It doesn't count ghosts.

And if the client discards them, they aren't there to be counted, and they become ghosts. And they bloat the database without bound. As David should know.

Not sure why you felt you needed to do that. The report I made was in part to show that things work as designed, in part to show it can look like a mess. It had nothing to do with the discarding problem. And nothing to do with the BOINC on that system, as they miss ten revisions.
