Error occurred when spinup the CLM4CN.

I was trying to spinup the CLM4CN using my own forcing, using a definite initial condition. While for the spinup process interrupted by some reason which I could not figure out.In the {caseroot} directory, the error told me to see the cpl.log.* file in the RUN DIRECTORY. When I see the cpl.log.* file, the last line of the file is only about the memory, and there was no error information in this file.I also see the ccsm.* file in the RUN DIRECTORY, and there was error information at the very beginning as follows:########################################## pio_support::pio_die:: myrank=          -1 : ERROR: pionfwrite_mod::write_nfdarray_double:         228 : NetCDF: Numeric conversion not representableforrtl: severe (174): SIGSEGV, segmentation fault occurredImage              PC                Routine            Line        Sourcelibc.so.6          0000003EFCC79110  Unknown               Unknown  Unknowncesm.exe           0000000000B25EF3  Unknown               Unknown  Unknowncesm.exe           00000000009DD601  pio_support_mp_pi         110  pio_support.F90.incesm.exe           0000000000957AD5  pio_utils_mp_chec          68  pio_utils.F90cesm.exe           0000000000A2575D  pionfwrite_mod_mp         228  pionfwrite_mod.F90.incesm.exe           00000000009F5FE3  piodarray_mp_writ         565  piodarray.F90.incesm.exe           00000000009F4630  piodarray_mp_writ         181  piodarray.F90.incesm.exe           000000000057C1FD  ncdio_pio_mp_ncd_        2316  ncdio_pio.F90cesm.exe           000000000051BDE8  histfilemod_mp_hf        2430  histFileMod.F90cesm.exe           0000000000516EFE  histfilemod_mp_hi        2909  histFileMod.F90cesm.exe           000000000049DDFD  clm_driver_mp_clm         775  clm_driver.F90cesm.exe           0000000000481A14  lnd_comp_mct_mp_l         585  lnd_comp_mct.F90cesm.exe           0000000000407BE5  ccsm_comp_mod_mp_        2802  ccsm_comp_mod.F90cesm.exe           000000000042639D  MAIN__                     91  ccsm_driver.F90cesm.exe           000000000040644C  Unknown               Unknown  Unknownlibc.so.6          0000003EFCC1D9C4  Unknown               Unknown  Unknowncesm.exe           0000000000406359  Unknown               Unknown  UnknownMPI process (rank: 1) terminated unexpectedly on c301-204.ls4.tacc.utexas.eduExit code -5 signaled from c301-204forrtl: error (69): process interrupted (SIGINT)####################################################Can somebody come into this kind of issue before, and know how to deal with this kind of issue?Thanks very much for your help.

This error indicates that you are trying to write a bad value (NaN) to the output file.    If you recompile and run in DEBUG mode you may be able to get more information as to where the NaN originated.
