[Vinay485]

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.

This appears to be an error in a (3rd party?) C runtime library. Google searching for px_pgout yields some informative links.

Look at this one: https://www.unidata.ucar.edu/mailing_lists/archives/netcdfgroup/2009/msg00463.html

And others for potential solutions.
