Compiing 4.3 was successful but took a long time

[thisisalloneword]

I am using 2020 Intel Compilers. The compilation took a long time ( ~ 2 hours ). It keeps hanging when compiling and reports crazy long times like this:

real 12m9.490s
user 12m4.535s
sys 0m1.441s

The system time would be small, but total time would be several minutes. It would do this many times. For example when doing this:

time mpiifort -o module_first_rk_step_part1.o -c -O3 -ip -fp-model precise -w -ftz -align all -fno-alias -FR -convert big_endian -I../dyn_em -I../dyn_nmm -I/gpfs/backup/software/app/weather/v4.3_intel/Build_WRF/WRF-4.3/external/esmf_time_f90 -I/gpfs/backup/software/app/weather/v4.3_intel/Build_WRF/WRF-4.3/main -I/gpfs/backup/software/app/weather/v4.3_intel/Build_WRF/WRF-4.3/external/io_netcdf -I/gpfs/backup/software/app/weather/v4.3_intel/Build_WRF/WRF-4.3/external/io_int -I/gpfs/backup/software/app/weather/v4.3_intel/Build_WRF/WRF-4.3/frame -I/gpfs/backup/software/app/weather/v4.3_intel/Build_WRF/WRF-4.3/share -I/gpfs/backup/software/app/weather/v4.3_intel/Build_WRF/WRF-4.3/phys -I/gpfs/backup/software/app/weather/v4.3_intel/Build_WRF/WRF-4.3/wrftladj -I/gpfs/backup/software/app/weather/v4.3_intel/Build_WRF/WRF-4.3/chem -I/gpfs/backup/software/app/weather/v4.3_intel/Build_WRF/WRF-4.3/inc -I/software/app/weather/v4.3_intel/Build_WRF/LIBRARIES/netcdf/include -real-size `expr 8 \* 4` -i4 module_first_rk_step_part1.f90

Is this normal with Intel compilers or something wrong with my environment. I did also try compiling 4.2.2 on another system with GNU compilers. That builts in just a few minutes
