I have never seen issues like this. It is more like a machine issue.
Have you ever successfully run the same case before?

I've finished running, luckily the results were quite good, nothing happened. but it takes a lot of time because the computer experiences not running in a few seconds. This often happens if I turn on the internet while running wrf.exe . I don't know why, I use a virtual machine to run.

What is probably happening is that your windows machine has 8 cores to run itself and any programs

you are allocating 6 cores of the 8 to the VM.

That leaves windows with only 2 cores to run background processes. Since the VM will probably max out the other 6.

In my experience with VM I try to only allocate around half of my available cores to it to get it to run properly.

1. Make sure to save all your data before trying these suggestions.
2. change the VM to 4 cores and run ./wrf.exe with all 4 cores. IT may cause the VM to freeze and not run
3. if that occurs try setting the VM to 5 cores and only use 4 cores with wrf.exe.

My guess is that the reason why everything is freezing up is that the cores are maxing out and the computer is slowing down the processes which causes that error.

Again this is my suggestion. If you want to wait to hear if @kwerner or @Ming Chen have any other suggestions too
