Multiple warn logs of "Choked at offset"

I know those logs are warnings but I think it's worth notice it.
Perhaps we may create multiple issues for each message type, you tell me.

I don't know the project well, just the general purpose, so I may miss something.
I'll try to respond to your questions ASAP.

### What installation are you running?

I am having issues for about a month in Home Assistant on a Docker container, the current version of the zeroconf dependency is `0.36.2`.

Installed version of Home Assistant : https://github.com/home-assistant/core/releases/tag/2021.9.6 (zeroconf version `0.36.2`)
But I've noticed it from the 2021.9 beta : https://github.com/home-assistant/core/releases/tag/2021.9.0b0 (zeroconf version `0.36.0`)

Logs below.
