Hello,
Apologies for the errors - one of our users sent out jobs with inconsistent input files, which generate the errors you got. He has stopped the original submission and proceed with the correct inputs.
Please abort all the tasks named workspace1* that you have received till early this afternoon.
Thanks for the quick feedback.
Cheers,
A.

Thank you for the info!
Can you cancel theses tasks on the server side to prevent them from being re-sent ?
Thanks!

I had loads of errant workspace1_hl13..... tasks today that failed after only a few seconds but this one, that arrived at 19:35 UTC, seems to be running fine. 4 mins in, 5% progress, 52 mins estimated remaining.

Hi Ray,
thanks for confirming that re-submission was successful.

Concerning cancellation of tasks, the operation is a bit difficult, as the study name (which is part of the task names) was not changed, making cancellation more surgical. Making out best not to kill any proper task.
Thanks!
A.
