CESM simulation crashing upon resubmit

Hi everyone,

I've been attempting to run CESM2.2.2 utilizing the F2000Climo compset and ne0CONUSne30x8_ne0CONUSne30x8_mt12 variable resolution grid. I was able to successfully run a startup simulation of 15 months from specified initial conditions, but upon resubmission, the simulation crashes immediately without any xml changes. I think this crash is happening maybe due to issues in the restart files, but I'm unable to identify what exactly is causing the problem. I've been able to find this warning in the CESM log file:

dec1238.hsn.de.hpc.ucar.edu 1882: MCT::m_AttrVect::indexRA_:: FATAL--attribute not found: "Flrl_rofsur" Traceback:

But according to the coupler log, it maybe has already processed something with this variable?

(prep_rof_merge) Summary:
(prep_rof_merge) x2r%Flrl_rofsur = = lfrac*l2x%Flrl_rofsur

The case run directory can be found here: /glade/derecho/scratch/leizhao/coupled_ctrl_nudge/run, and the case directory itself is located here: /glade/work/leizhao/lgray/coupled_ctrl_nudge

Changes to the xml files for this case's startup run include: ./xmlchange PIO_VERSION=1,STOP_OPTION=nmonths,STOP_N=15,RESUBMIT=7,RUN_STARTDATE=2006-01-01,CONTINUE_RUN=FALSE,ATM_NCPL=288. For this particular run, no changes have been made to the code of CESM itself. Any help on why this simulation doesn't want to restart would be greatly appreciated!
