CESM run stuck at remap (shr_strdata_init_mapping) calling shr_dmodel_mapSet

Hello!

I am facing problems when using high-resolution atmospheric forcing (1440 x 721) in the datm component while running NEMO-CICE configuration.
Initially, with my default flags for compilation, it showed a segmentation fault.
The message was "[n086:344621:0:344621] Caught signal 11 (Segmentation fault: address not mapped to object at address 0x2ae430e86680)"
It was also producing a core.* file in the end.

Subsequently, I added a flag -heap-arrays after which it is not getting out of the process but stuck for an indefinitely long time while
remapping the first file from the data stream at
remap (shr_strdata_init_mapping) calling shr_dmodel_mapSet

Also, it should be noted, that if I use any other low-res forcing with its concerned domain.lnd.* file it is working perfectly fine.

I will be highly obliged if anybody can help me in this matter.

Thanks in advance!

I'm guessing you are running out of memory for the high resolution case. So you likely need to give your simulation more processors. Most of the memory in our system scale with the number of processors, so you likely need to increase how many you are using.
