Changes between Version 1 and Version 2 of Ticket #31515, comment 20

v1	v2
1	1	Well, we would have to find exactly where the bug is first before fixing it. Nothing I know of in my quick glance through the code made it obvious where it could be; we seem to correctly handle the `close_old_connections` call even in Django 3.0 ASGI mode (not calling `close_old_connections` is often the cause of this bug).
2	2
3		I never figured out why during Channels development, but the MySQL backend seems specifically prone to these sorts of issues even when it should be fine. I think if you set a non-zero MAX_AGE it should clear itself up, if you can take that operationally, otherwise I think you may have to run on WSGI rather than ASGI for now (unless we track down exactly what is doing this)
