Step: error in barotropic with branch run

Hello, 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 POP2VOLUME AND TRACER BUDGET INITIALIZATION:          ========================================      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  Global Time Averages: 01-01-1973 01:00:00 VDC_BCK:   0.160397863902526 VVC_BCK:    1.60397863717241 (io_pio_init)  create file ./BG20TRCN_f09g16.001.pop.h.once.nc  tavg file written: ./BG20TRCN_f09g16.001.pop.h.once.nc (time_manager) ocn date 1973-jan-02, 0.000000E+00 sec  Global Time Averages: 01-02-1973 00:00:00 SST:    18.4008654281061 SST2:    445.822915436544 HMXL_2:    5452.14325234913 XMXL_2:    5602.30741039655 (io_pio_init)  create file ./BG20TRCN_f09g16.001.pop.h.nday1.1973-01-01.nc  data appended to tavg file: ./BG20TRCN_f09g16.001.pop.h.nday1.1973-01-01.nc ------------------------------------------------------------------------ POP Exiting...POP_SolversChronGear: solver not convergedPOP_SolverRun: error in ChronGearPOP_BarotropicDriver: error in solverStep: 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,-Raymond SellevoldPhD studentDelft University of Technology
