CCM guys,

While runing CCM3.6.6 on LINUX clusters with just 2 nodes, the
initialization seems finished. However, just some steps later, the
following error message prompts:

      **** Summary of Logical Unit assignments ****

   History file number 1 = 31
   History file number 2 = 32
   Restart dataset unit (nsds) = 1
   Master regeneration unit (nrg) = 2
   Regeneration dataset units (nrg1) = 3 4 7 8 9
   Abs/ems unit for restart (nrg2) = 10 11 12 13 14
   Regeneration units for hist file 1 = 17 18 19 20 21
   Regeneration units for hist file 2 = 22 23 24 25 26
            1 (<--lat cycling in scan1bc.F)
Segmentation fault
rm_l_1_3936: p4_error: net_recv read: probable EOF on socket: 1
bm_list_26145: p4_error: net_recv read: probable EOF on socket: 1

The compiler and linker are mpif90 from mpich and pgf90, they all work
well. I traced the code and found the subroutine linemsbc could not be
executed in /src/dynamics/eul/scan1bc.F even one step. The number 1
mentioned above is lat cycling in scan1bc.

Any suggestions especially from NCAR CCM group?

Thanks,

Ping Liu
