metgrid.exe makes file system unwritable

[imbakassinn]

I am trying to run metgrid.exe on ERA5 pl files. ungrib runs without issues and metgrid runs ok for some time. After some time metgrid.exe crashes. The last lines of metgrid.log follow:

WRF_DEBUG: NetCDF error: Read-only file system
WRF_DEBUG: NetCDF error in ext_ncd_open_for_write_begin wrf_io.F90, line 1373
ERROR: Error in ext_pkg_open_for_write_begin.
Note: The following floating-point exceptions are signalling: IEEE_OVERFLOW_FLAG

This causes my file system to go to read only and I have to restart to be able to use the computer again. It could be a problem with the input grib files but metgrid should not put the file system to read only mode.

I've got WPS 4.2 compiled with gfortran, serial running on Ubuntu server 18.04. I had the same problem with WPS 2.0.3

If you haven't already done so, could you post this question to the WRF support forum at https://forum.mmm.ucar.edu/ ? We generally use GitHub Issues to track problems that can be traced to a specific piece of code, and that can be fixed with a code change, while the forum is used for support inquiries.
