CAM4; ZM_CONV IENTROPY: Tmix did not converge

Hi,I'm trying to run slabocean aquaplanet configuration with 2xCO2. The model crashed in year 6. It seems the model produced a value that exceeded its limit. The error massage is pasted below.I saw a similar issue reported on the forum before. The suggested solution is to increase nsplit, nspltrac and nspltvrm, which I tried and didn't work. The model I'm running is CESM1.2.1 with CAM4.
