    18 == 16 February 2018 : METO: eORCA1 and eORCA025 occasional failures with !NaNs  
     18== 16 February 2018 : METO: eORCA1 and eORCA025 occasional failures with !NaNs (SOLVED in r9415)

    2020I'm getting occasional failures with a segmentation fault in icb_ground in eORCA1 and eORCA025 built from the latest dev_merge_2017 branch (after several months of integration). I think icb_ground is acting as an error trap for NaN values produced in ice_dyn_rhg_evp. I will try to trace it back further next week. (Dave Storkey).

    2222'''Update 21 Feb:''' This looks like some kind of instability which doesn't get picked up by the checks in stp_ctl. There is very thick ice (~100m) and a negative top-level thickness (e3t) at a single point which I think results in a divide-by-zero in sbc_isf_div. It looks different to the instability in the the 300 timestep ORCA2LIM3PIS_ST run in SETTE, which doesn't show any abnormally thick ice.

     24'''Update 21 March:''' The Ice thickness is not "low capped" by rn_himin before thermodynamics is running. In case of very small ice thickness, the ice diffusion blow up.
