CAM5 segmentation fault (F_1850-PDAY_CAM5)

[scorvec@uwaterloo_ca]

HI,I am running a AMIP4K type simulation using the CAM5 (from CESM1.2.2) using the F_1850-PDAY_CAM5 compset with the f19_f19 resolution. I have increased the default AMIP SSTs uniformly by 4K, and changed a few parameters in the ZM convective scheme. The run starts in "1979" and gets mid way through 2001 and crashes with a segmentation fault (this error is reproducible). I have run the exact same type of simulation on the same machine without changing the parameters in the convective scheme and it runs successfully. Below is the only error message I receive (in cesm.log.*):forrtl: severe (174): SIGSEGV, segmentation fault occurredImage PC Routine Line Source             cesm.exe 0000000001371292 tp_core_mp_xtpv_ 469 tp_core.F90cesm.exe 000000000136A299 tp_core_mp_tp2c_ 119 tp_core.F90cesm.exe 000000000134C5E2 sw_core_mp_c_sw_ 309 sw_core.F90cesm.exe 00000000012B4DE5 cd_core_ 732 cd_core.F90cesm.exe 00000000010D1CD2 dyn_comp_mp_dyn_r 1822 dyn_comp.F90cesm.exe 0000000000F1C350 stepon_mp_stepon_ 422 stepon.F90cesm.exe 000000000048B721 cam_comp_mp_cam_r 250 cam_comp.F90cesm.exe 000000000047EE28 atm_comp_mct_mp_a 561 atm_comp_mct.F90cesm.exe 000000000040DB34 ccsm_comp_mod_mp_ 4079 ccsm_comp_mod.F90cesm.exe 000000000042B6DD MAIN__ 91 ccsm_driver.F90cesm.exe 0000000000407F6C Unknown Unknown Unknownlibc.so.6 00007FFFF670BD5D Unknown Unknown Unknowncesm.exe 0000000000407E69 Unknown Unknown Unknown Has anyone encountered this error before or have any theories as to what might be causing it?

Hi Shawn,I also have some issue running this compset, but in my case I can not even let the model start to run... I described the problem at https://bb.cgd.ucar.edu/runtime-error-issue-f1850-pdaycam5-0Not sure if you have any idea why the model won't run in my case as we have similar settings. Thanks,Bo
