Python "[WinError 233] No process is on the other end of the pipe" on print statement

Question

I wrote a Python script that goes forever in a while true loop and runs other Python scripts by interval like this:

while True:
        now = time.time()
        for command in self.commands:
            if (command.last_called_timestamp + command.interval) < now:
                command.last_called_timestamp = now
                command.run_command_parallel()
        time.sleep(0.1)

And the run_command_parallel method is like this:

def run_command_parallel(self):    
    thread.start_new_thread(os.system, ("python some_other_script.py", ))

The script works fine for several days. However, after 3-4 days I always receive an error from some random print statement of scripts that run in separate threads: "[WinError 233] No process is on the other end of the pipe". The script with the while loop also gets terminated. Any idea on why I receive this error and why the script with the while loop gets terminated? Or an alternative solution that can work in Python (without using batches or windows task schedulers)?

Update:

There is a discussion on Blender's forum about [WinError 223]. It seems like an add-on in Blender also causes this error. The answer of 'Pedro A.' says that a line in the code which tries to use "os.system" causes this error. When this line of code removed the add-on works fine and throws no more error.

Still couldn't find a fix or real cause behind it. Any help will be much appreciated.

Answer 1

I also ran into the issue. After trying out multiple ways to fix it, what helped me was restarting the PC. It solved my issue.

I know its kind of anticlimactic but that is what helped me and for some reason there is not enough information regarding this error in python.
