1 year ago The solution to avoid this problem was to make create_stream() a blocking function, because it must stay alive (the thread) till the new stream (and thread) is ready. this is not cool if you manage a lot of streams. so we added the parameter high_performance to bypass this mechanism.
Are you using high_performance in your ubwa instance?

1 year ago Thank you for the quick reply.
I am not setting the high_performance parameter in my code. According to the documentation, the default is False so it should be a blocking function.

1 year ago Can you test please adding this code to the end of your script:
while True:
time.sleep(1)It would help to get a script that is producing this error on your system.

1 year ago Okay, I am going to test this as well as the effect of using python 3.8. Also, I will try to replicate the error with a script that I can share. As the error usually only occurs after a couple of days, it might take a while until I can come back to you.

1 year ago The script attached reproduces the error on my system. It took about 3–4 days until it stopped with the same error message as mentioned above. Running it in python 3.8 did not resolve the issue and also adding your proposed while loop at the end did not help.

Issue
First of all, thank you for sharing this very useful library! Unfortunately, when using the "userData" stream, the connection seems to disconnect regularly after a couple of days with the message: "RuntimeError
error: 11- error_msg: cannot schedule new futures after interpreter shutdown". I only experience the issue with the "userData" stream. When using the "aggTrade" stream, everything seems to be fine.I saw that similar issues were posted already where python >= 3.9 could have been the problem, so I will test running the program with 3.8 to check if the issue still occurs.
