Python 3.8: "An open stream is being garbage collected"

dnadlinger opened this issue · 2 comments

On 398f6be, the controller manager prints these messages from time to time, in groups of 10:

ERROR:ctlmgr(hoa2mstr):asyncio:An open stream object is being garbage collected; call "stream.close()" explicitly.

Might be related to controllers exiting due to failure.

(Still need to properly debug this, of course.)

Is this still happening?

Doesn't seem to have occurred since 2021.
