CM4 crashes due to incorrect initialization after reading old ice restart file when compiled with infra/FMS2

Closed this issue · 0 comments

We were trying to restart CM4 using old cmip6 picontrol restarts and a recent MOM6 tag.
When compiling with infra/FMS2 we got the following warnings:

WARNING from PE     0: categorize_axes: Failed to identify x- and y- axes in the axis list (xaxis_1, yaxis_1, Time) of a variable being read from INPUT/ice_model.res.nc

Subsequently the model crashed with:

FATAL from PE   321: compute_qs: saturation vapor pressure table overflow, nbad=    231

The same exact model ran fine when compiled with infra/FMS1.

I have a simple fix for this and I'll make a PR shortly for review.
