socket.send() raised exception + Server sent "-404"

[shamloo]

Hello and thanks for this good module.
I use your module to log in with multiple bots and use the mtproto methods.
And I use it with the supervisord as a service.
i am getting some errors again and again that when i restart the script errors gone but after a few hours it will happen.
It would be great if these errors could be fixed in this module as well.
Errors:
Server sent "-404"
and
socket.send() raised exception.
Edit:
in this module there is one instance , why i am getting below error:
sqlite3.OperationalError: database is locked
