Same for me. Running Home Assistant Core in Docker on Ubuntu on Mac. :slight_smile:

I think its a HACS Custom Component. Don’t know how to debug this

4

Same for me as well. I have disabled two HACs integrations ( Remote-Home Assistant and Google Wifi) but I am still running the HACS integration itself as well as ResMed (CPAP data Integration). I am getting the same series of 1 minute “spam” message:
E0306 13:26:36.232213328 242 fork_posix.cc:70] Fork support is only compatible with the epoll1 and poll polling strategies.

Issue appears to coincide with the latest Core update (2022.3.1).

Same here , since last update log gets spammed with the fork_posix error Âż

6

Yep. Only 35 messages in the last 5 minutes. No idea where to even look. Tried disabling things to get it to stop.

7

I also have this message, I did not notice it before migrating from Home Assistant container to Home Assistant core.
But I think it is because I did not look at the console output with Docker, nothing is in the log file

One more info on this?

I started to notice it from 2022.3.5 (but it may have been there before)
I’m not yet sure if it si affecting some functions… keep you posted.

Possibly related to Bump grpcio to 1.44.0 by allenporter · Pull Request #66787 · home-assistant/core · GitHub. Some discussion here: [Bug] Upgrade to gRPC 1.46 once it's released (which fixes fork support) · Issue #22518 · ray-project/ray · GitHub.
Can we downgrade to grpcio 1.43 while we wait for a fix too?
(I manually downgraded by running pip install --upgrade grpcio==1.43.0 and it looks good so far.)

I’m getting this now with 2022.6.3 upgrading from 2022.5.5 core. Running in docker on unraid.

13

Yes and rpi4 64bit.

Same here running Hass OS on an intel nuc. I noticed this due to the fact hass became unresponsive and then the supervisor rebooted hass. Whether the two are related or not i am unsure, but i didnt have this message nor issues with hass before updating about a month ago. i was on 2022.01 for many months as i was underway and all was well.

Currently on:

  • Home Assistant Core 2022.6.4
  • Home Assistant Supervisor 2022.05.3
  • Home Assistant OS 8.1

I recently upgraded to 2022.7.7. The log spamming is back. I again reverted to grpcio==1.43.0 and the spam is gone.
