I did a quick test with python3.6 and found a similar error but unable to see when running with 3.7.

Can you try the codes with Python 3.7 or 3.8?
I suspect that it might be the same issue mentioned in this post. It seems to be a problem with the conflict version of asycio lib but I can't confirm.

Hello @Alena.Melnikova

What is the environment (Jupyter Notebook or Console) and Python version that you are using?

I am testing your code with Python 3.7.7 in Jupyter Notebook for an hour but I cannot replicate the issue in my environment yet.

@Alena.Melnikova

I also tried your codes on Jupyter notebook but still not see issues as well. I can run for more than 1-2 hours. Note that I just print the fields out.

Do you have any chance to try your account with another example and did you found the token issue?

I'm not sure that is there any exception when you parse the field data so it interrupts the whole process?

Hi @moragodkrit and @Wasin Waeosri

Thanks for your responses!

I run in PyCharm with Python 3.6.8.

I also tried an example with rdp.ItemStream:

item_stream = rdp.ItemStream(
    session=session,
    domain='MarketByPrice',
    name="BB.TO",
    on_refresh=lambda item_stream, event: display_event("Refresh", event),
    on_update=lambda item_stream, event: display_event("Update", event),
    on_status=lambda item_stream, event: display_event("Status", event),
    on_complete=lambda item_stream: display_event("Complete", "")
)

item_stream.open()
while True:
    try:
        asyncio.get_event_loop().run_until_complete(asyncio.sleep(1))
    except (KeyboardInterrupt, SystemExit):
        rdp.close_session()
        break

and get the same issue in 9 minutes after start script:

>>> Status event received at 18:54:01.305752
{'status': <StreamState.Open: 3>, 'code': 'Open', 'message': '*All is well'}
...

There is nothing special in parsing data. Just print it:

def display_event(eventType, event):
    currentTime = datetime.datetime.now().time()
    print("----------------------------------------------------------")
    print(">>> {} event received at {}".format(eventType, currentTime))
    print(event)
    return

Can it be a problem with my account? I use a machine account.

@moragodkrit You're right! I tried Python 3.7 and it works without intervention 3 hours already! Thank you!

I also noticed that I can't run one more app in parallel. In a few minutes, the first app failed with error

[Error 400 - access_denied] iPlanet session has been expired. 

Even if I use different app_key. Does it mean I can't run a few apps for one account?
