issue still idle on some server and channels

Hello,
I have a bot that is able to connect and sit idle in spaces. However on certain channels with in a server the bot will get disconnected some time after joining with a server message of Max SendQ exceeded. How do i fix this?

The report does not name files, tests, or entry points. Start by reproducing the disconnect on the affected IRC channels and trace how the library handles the server's "Max SendQ exceeded" message; done means identifying the cause and confirming a fix for idle connections.
