I got two WUs from batch 564 hadcm3s issued April 2017. Do not know whether it's been resolved.
hadcm3s_83yo_201412_120_564_011007443

Edit: Are these relevant at all, they were issued 2 years ago (2017) and were resent two years later. Where were they hanging? I have a 3rd one running ok so far, but should I abort it?

I doubt that the output from those models would be used. As you said, it was 2 years ago. About 60% of those work units from that batch completed successfully. If they had needed more output, they probably would have issued a new batch for it rather than waiting 2 years for the stragglers to come it.

However, I will ask Sarah if these tasks should even be regenerating. It seems odd.

Thanks, it seems few hundred of this model were generated on 11 march and can be seen at the Enhanced Climateprediction (CPDN) status page of Tullus. I will keep running the 3rd WUs at least until the first zip.

That would explain the increase in the number of hadcm3s tasks running on the Project Status Page. I looked for and couldn't find evidence of a new batch that had escaped the batch list and other places where new work is discussed.

It uploaded its 2nd zip, no second trickle and having in mind the output will not be used I will abort it.
