Still experiencing the same error repeatedly, which is blowing up the log.

Log size is 1,793 KB in just under 3 hours, can anyone guide me as to how I may be able to troubleshoot or correct this error?

First error below:

@manuel-jrs @oldfart101
Which notify component are you guy's using?

oldfart101 · 2018-04-01T18:36:53Z

don't understand the question

Coolie1101 · 2018-04-01T18:44:31Z

Are you sending messages/images from HA to somewhere?

manuel-jrs · 2018-04-01T18:55:29Z

@Coolie1101 I'm using telegram platform.

Coolie1101 · 2018-04-01T19:22:43Z

@manuel-jrs
Same here, did you upgrade to 0.66.0 and still seeing the same errors?

oldfart101 · 2018-04-01T19:25:19Z

only MQTT, errors still there after upgrade to 0.66.0

Coolie1101 · 2018-04-01T19:28:41Z

@oldfart101
Thanks, thought it was only related to Telegram.

Did you upgrade to 0.66.0 and still seeing the same errors?

oldfart101 · 2018-04-01T19:30:16Z

yes, P.S. does Alexa via cloud count?

manuel-jrs · 2018-04-01T23:16:53Z

@Coolie1101 I upgraded it to 0.66 and still the same errors.

lucaspnw · 2018-04-10T21:12:05Z

Same problem here, pretty barebones install. Just a single zwave USB stick and a few zwave PIR sensors set up. no automation, no triggers/events. Running hassbian on a RPi-2b.

Version: 0.66.1

It started after about 24 hours total uptime.

Could it be because aiohttp==3.0.6?

Anyone know what "RuntimeError: File descriptor ##" means or refers to?

After stop, disabling influxdb, start, no more error.
then i re-enabled influxdb, and also no error.

Not fixed yet. The error is spontaneous. Only one problem because of it - my log file blowing up to 17Mb at day....

rotcop4u2 · 2018-06-13T09:16:17Z

I am getting the same error. i went 48 hours with out it last time, but then it hit hard. the only way i could stop it was to reboot my RPI. Log got almost 700MB in 15 minutes.

I just noticed this for the first time today. It doesn't appear to have happened prior to 0.73.2. Other versions I was on recently:

0.73.1 - I was on briefly.
0.71.0 - for quite a long time.

I get the same issue on 0.79.1, followed by a full HA crash, along with:

python: src/unix/core.c:896: uv__io_stop: Assertion `loop->watchers[w->fd] == w' failed.

Googling that particular aiohttp error didn't turn up a fix.

Edit: I do have the camera component loaded and displaying an image on the Lovelace dashboard.

mykola-dev · 2018-10-10T07:37:16Z

This is ~~ridiculous~~ sad. Today morning i got spammed again. My 32gb card is 70% full and CPU is overheated (72*). The error log message appears in the log several hundreds times per second!

Btw, i have cameras in my setup and Lovelace enabled too. I can provide the configs.

awarecan · 2018-10-12T04:34:18Z

@deviant-studio what camera are you using?

mykola-dev · 2018-10-12T07:08:46Z

@awarecan i have several, but suspect this one https://ru.aliexpress.com/item/BESDER-Yoosee-IP-Camera-Wifi-1080P-960P-720P-ONVIF-Wireless-Wired-P2P-CCTV-Bullet-Outdoor-Camera/32793309300.html
since its resolving time is the worst (until image appears in the card), and sometimes image doesn't appear at all. in these moments my hass instance is going crazy and spams the log with errors.
I use all my cameras in jpeg mode, like http://url-to-jpeg-image

awarecan · 2018-10-12T07:35:44Z

I mean what HA camera platform are you using? https://www.home-assistant.io/components/camera.generic/?

mykola-dev · 2018-10-12T07:39:24Z

@awarecan yes, all my cameras are generics

upd: sorry for misinformation. the problematic camera is running under ffmpeg platform. i was unable to run it under generic or onvif (despite it supports onvif)
here is the config

- platform: ffmpeg
  input: 'rtsp://192.168.1.111:554/onvif2'
  name: outdoor 3

It did change the code no error so far. However, I do not know what did trigger the error. So I have to wait for a couple of days

signaleleven · 2018-10-16T17:35:11Z

I just noticed the same. No idea what triggered it.

awarecan · 2018-10-16T17:41:53Z

@signaleleven could you please try to apply my patch?

bbrendon · 2018-10-16T17:57:12Z

Does this issue only occur for people with cameras in the HASS GUI? I have a few cameras, but I almost never click the Tab in the GUI where they are located which might be why this issue has only appeared for me once (that I have noticed anyway).

signaleleven · 2018-10-16T17:58:19Z

In my case, yes, I have some cameras in the gui, and one is not working (for other reasons). I will try to reproduce it. If I manage to reproduce it reliably, I will apply the patch.

signaleleven · 2018-10-17T21:13:27Z

@awarecan It happened again (good thing I set up an alarm on protracted high CPU usage :) ) and I applied your patch. I use hassio and I had to edit the file within the container. A simple container restart preserved the change. It will not survive a container recreation but until the next upgrade it should hold.

pagenoare · 2018-10-18T19:04:02Z

@awarecan just wanted to confirm that your patch has worked perfectly for me. Thanks much!

xatr0z · 2018-10-20T21:02:59Z

I dont have any camera's and still have the same error. Didnt saw it before, cant think of anything that triggered it (only tried some light automations today).

I will try the patch

This worked for my new installation. I had the same errors, probably related to how I have pages open on my ipad and iphone. None since applying this change.

mykola-dev · 2018-10-30T09:19:20Z

On 81.1 i don't have errors in the log so far. but still got spontaneous cpu full loads, and the only cure is to restart. Can't say for sure if it's same issue since my log is empty.

signaleleven · 2018-10-30T09:31:14Z

I also don't have the flood of logging anymore (I think already in 0.8), but I noticed that when the CPU jumps to 100% it INVARIABLY goes back to normal after exactly 2 hours.
And at the same time I get exactly ONE message in the log.

I applied the patch but of course I lost it at every upgrade, so I am living with the problem for now (this made me jump from a Rpi to an Intel NUC so I can survive)

(I just noticed that in my screenshot above the CPU usage goes down after more than 2 hours. But I must have retriggered the problem by browsing the UI while the problem was present. If I leave the UI alone, it's always going back to nominal in about 2 hours)

signaleleven · 2018-10-30T09:32:49Z

@mstovenour what do I remove or add? this is what I have

You have to invert the two blocks

     if registered:
         loop.remove_writer(out_fd)

and

        if fut.cancelled():
            return

Frankster-NL · 2018-10-31T11:00:49Z

Having this same issue since I added 2 onvif camera's (which aren't working)

Relevant configuration.yaml

 - platform: onvif
    host: 192.168.1.1.10
    name: Cam
    port: 8000

mykola-dev · 2018-11-06T08:31:21Z

Still exists on 81.6

But logs are empty. Nothing suspicious. Reboot helps but only for couple of hours. If i dont use UI intensively it can work normally for days.

I use one foscam camera and this error seems to have started after I implemented a snapshot automation to email a picture from the camera. I'm on 0.81.6, RPi3 / Hassbian.
