Hello
I noticed my CPU was 100% due to HA and I have emptied my MYSQL database and still it persisits. Any idea what I can do to see what is causing it please? I stop the docker and cpu drops right off. So I know it is something in HA
Cheers
Mark
tip: if you press “c” in top, you can see the whole command-line. But I’m sure it will show homeassistant. Could be any number of things. What version are you running? Any idea if this is new or could be an exciting pre-condition?
p.s.
It should not really matter whether you run it in docker or not, you could check but running it in an virtual-env if you know how to do that.
cheers yeah just says home assistant. I am running the current version and I did have this issue a few days ago
You could try:
strace -p 27189
and have a look if you see anything funky going on… It’s like looking into the matrix, sometimes you can see a glitch

That could be something, but could also be a side effect… See: https://blog.packagecloud.io/eng/2015/11/15/strace-cheat-sheet/
if you “grep them out” (add
| grep -v futex
is there anything else weird you see?
rolled back to Home Assistant 0.105.4
still the same… arrghh
Yeah, I don’t think it’s the version, more likely a device that’s acting up.
thanks for the replies nothing obvious, but I guess time to start stripping crap out of my config

I have tracked it down to the camera STREAM component. I removed the 1 camera stream I had setup and we are back to normal I have 4 other cameras setup but not using stream.
Didn’t have this issue with it until a few days ago… strange
Which HA version are you using? 0.106.x?
yep and 0.105… I remove stream and all is back to normal.
