flask用gunicorn启动后 ,过一段时间会无法访问?500

Question

升级到了最新版本flask-script,用gunicorn启动flask,刚开始启动时是好的，但等一会儿后，再访问，就无法访问了:

代码如下：

class GunicornServer(Command):

description = 'Run the app within Gunicorn'

def __init__(self, host=host, port=port, workers=workers,
             worker_class="sync", daemon=False):
    self.port = port
    self.host = host
    self.workers = workers
    self.worker_class = worker_class
    self.daemon = daemon

def get_options(self):
    return (

        Option('-H', '--host',
               dest='host',
               default=self.host),

        Option('-p', '--port',
               dest='port',
               type=int,
               default=self.port),

        Option('-w', '--workers',
               dest='workers',
               type=int,
               default=self.workers),

        Option("-c", "--worker_class",
               dest='worker_class',
               type=str,
               default=self.worker_class),

        Option("-d", "--daamon",
               dest="daemon",
               type=bool,
               default=self.daemon)
    )

def run(self, host, port, workers, worker_class, daemon):
    from gunicorn.app.base import Application

    class FlaskApplication(Application):
        def init(self, parser, opts, args):
            return {
                'bind': '{0}:{1}'.format(host, port),
                'workers': workers,
                'worker_class': worker_class,
                'daemon': daemon
            }

        def load(self):
            return app

    return FlaskApplication().run()
manager.add_command("run", GunicornServer())
