Message 46694 - Posted: 24 Jul 2013, 12:07:19 UTC

Had 3 models last 2 weeks that got near end and then stopped running -showed running - BOINC manager showed as running but task manager showed not using any CPU. Graphics display stayed stuck at same point for a day or two (real days -- model days never progressed.) After a day or two killed all 3. Two of them at 99% plus one in the 80% range.
Seemed weird that tasks would show running in BOINC but graphics screen showed same point for days and system showed no CPU usage.
Killed the jobs and going on - but strange strange strange.

I've had that too, with one model.

A system reboot fixed it, allowed it to carry on and finish successfully. (I needed to apply some updates anyway...)

Unfortunately the ones I had were not helped by reboot.

I've got one I think is doing the same - stuck at the same 25.193% for about 10 days. After each reboot I lose "elapsed time"; last night it had done 156 hours and this morning it had done 152 hours. After reading this thread I see it doesn't show up in top, so I've killed the job.

Ah, the dreaded "Failure at zip time" problem.

Sorry Les, I'm not familiar with that. Could you send me a link to an explanation?

There are posts all through this board about how touchy this type of model is to being interrupted, especially at all of the 25% points.
And then there's a few that complete, and then just run in a short loop just past the finish point.

There's a short, fairly recent, thread here about the former, and one about the later here.
