Multiple Errors

Configuration

Hello,
I see way too much errors at the logs.All errors are the same and the exceptions are happening nearly every second.
The Error message is this:
Wed Sep 12 2018 16:44:22 GMT+0300 (GTB Summer Time)

Does anyone know why is this happening?

The same is happening here after having upgraded to 0.78.3.

I have not found anything being broken so far - except those error messages appearing in the log.

RuntimeError: File descriptor 25 is used by transport <_SelectorSocketTransport fd=25 read=polling write=<polling, bufsize=0>>

Do you use anything that communicates over the web? Like a sensor? Appears to be an issue with that. It’s possible that whatever is causing the problem doesn’t update when that error occurs.

Yes, but how to find out which one?

turn on debugging and see when it fails. You might be heading down a rabbit hole.
