There seems to be a bug in detecting the zombie process

[fanisky]

It doesn't happen every time, but it happens every day, causing the main program to exit

Code file: stateless-manager.py

Occurrence code line: if psutil.Process(pid).status() != 'zombie':

Code snippet:

    logging.info(f'Clearing zombies')

    for job in jobs:
        non_zombie_work = []
        for pid in job.running_work:
            if psutil.Process(pid).status() != 'zombie':
                non_zombie_work.append(pid)
            else:
                del running_work[pid]
                job.total_running = job.total_running - 1

        job.running_work = non_zombie_work

Exception should be caught. Or first determine whether the process number exists?
