Nemo postproc error in coupled run

1

Hi,

I’ve had a recurring NEMO postproc error which has appears after 18 months of a coupled run (6m resubmission). Is this a disk quota error? The suite is u-ds207 and it is up to date with commits.

Hi James,

Looks like you’ve fixed the OOM now by requesting more memory with the --mem=25G directive. That was what I was going to suggest. :grinning_face:

Let me know if that isn’t the case.

Cheers,
Ros.

Thanks, Ros, I found your advice to Charlie. I should have looked harder!

Cheers,

James
