[vinay]

Team is facing the following error abruptly in the middle of a simulation which is submitted on HPC using WRF-Chem version 3.9.1

ERROR:
"wrf.exe: posixio.c:283: px_pgout: Assertion `*posp == ((off_t)(-1)) || *posp == lseek(nciop->fd, 0, 1)' failed.
forrtl: error (76): Abort trap signal".
(plz refer the screenshot)

and once we resubmit the job, its running fine without showing any error and run is successful.

Would appreciate if someone can clarify me, how to resolve the error or reasons for occurrence.

Hi Vinay,
I am having exactly the same isssue running WRF on a Cray machine with compilation done using Cray Fortran. Did you manage to find out what causes this and/or a potential solution?

Just an update, this was related to a LUSTRE system configuration issue in my case.

Hi Jatin_kala,
What kind of Lustre configuration issue in your case? I hit the same error.
Thanks,
