Step: error in barotropic with branch run



I am trying to set a B (BG20TRCN) branch run using CESM1.0.5 on cheyenne with the f09g16 resolution. The restart files come from a run using CESM1.0 on yellowstone. All components are able to run for one day, but after the first the day I get the following error from POP2



      volume_t (cm^3)           = 0.132514028792E+25

      SUM [volume*T] (C   cm^3) = 0.429661165056E+25

      SUM [volume*S] (ppt cm^3) = 0.460067132939E+26

Step: error in barotropic





I looked around here for some suggestions how to solve it (change dt_count from 23 to 26, check the format of restart files), but this did not solve my problem.

Does anyone know how to solve this problem?


Thanks in advance,
