Error from DA cycling (segmentation fault)

Post by cyh082 » Fri May 28, 2021 4:22 am


I conducted DA cycling experiments, using WRF and WRFDA version 4.2.2.

I assimilated PrepBUFR (conventional), GPS RO, and radiance observations over Arctic domain.

I successfully did DA cycles for 5 days, but I got the below error when running WRFDA, from the 22nd cycle.

forrtl: severe (174): SIGSEGV, segmentation fault occurred

I attached "rsl.error" file.
I used a total of 10 nodes, and each node has 28 cores.

Could you help me to resolve the above issue?

Thank you.
