Initially the nameko shell is able to communicate with the nameko service. The service is a simple hello world:

```auto
class GreetingService:
    name = 'greeting'
    @rpc
    def hello(self):
        return f"{datetime.today()}: hi"

```

Within the shell, I can call hello in a loop without problems. If I wait 5 minutes or more to call hello then the shell hangs indefinitely.

```auto
helo=n.rpc.greeting.hello
>>> helo()
'2022-10-03 12:40:12.628285: Hello, alarm device count=936'
>>> helo()
***hangs here***

```

The second helo will be stuck and impervious to keyboard interrupt. I have to kill the shell process.  
Do you have any ideas why this is occurring?  
Or do you have any suggestions for troubleshooting?

Environment:  
nameko - 2.14.1  
Windows 10  
python3.9.5

My guess is that the MQ connection may have been broken
