[MITgcm-support] build errors for llc_1080

[Dimitris Menemenlis]

Hi Ryan, often when I have encountered similar error situation,
it was caused by a file that was incorrectly transferred and was either
incomplete or contained some nans.
Is it possible that your atmospheric fields were not transferred correctly?
Maybe a checksum of fields on pleiades vs those that you are using would help?

The other possibility is a configuration issue, especially with pkg/seaice
Some of these large values of fluxes that Jody points out below could be from melting or
freezing of sea ice on first time step.  One quick way to exclude a pkg/seaice
problem is to temporarily set useSeaice=.FALSE. and see if you get past the first time step.

I have many more suggestions, but please try the first two above first,
before I bombard you — and if all else fails, I will try to reproduce your problem locally.
