Bug description:
Hello, after upgrading our application to 3.12.1 that uses aiohttp to download stuff via HTTPS as well as connects to some RabbitMQ servers via ssl, we get this spurious exception to stderr, dozens-hundres of them in close succession.
They happen after several minutes of running (so after dozens of ssl connections are used).
Unfortunately, I can't tell what is the culprit, the trace contains nothing other than the runtime :( I can provide more info if you give me some pointers on where to look. It looks like write-after-close, but the "writing" is done by internal asyncio mechanisms.
