XKNX UDP Error killing HASS log

[firefrei]

Hey, I got a problem :-)

I use xknx with Hass and it is filling up my hass logs with the following error message:

...
During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "uvloop/cbhandles.pyx", line 52, in uvloop.loop.Handle._run

OSError: [Errno 9] Bad file descriptor

I just deleted the hass log file with about 65GB of spam. This filled up my servers hard disk :-D

My xknx config in hass is pretty minimalistic:

knx:
  tunneling:
    host: '192.168.1.66'
    port: 3671
    local_ip: '192.168.1.60'

I've noticed the problem in Hass Version 0.60 and 0.61

Can you help me with this issue? Cheers :-)

I'm using the official HASS docker image that ships Python 3.6.4 and xknx 0.7.18

Hmm,

what I don't understand, how UDPClientFactory can be initialized without having the self.xknx object being initialized:

https://github.com/XKNX/xknx/blob/master/xknx/io/udp_client.py#L42

Any ideas?

(There is also another issue for a better handling of UDP errors ... https://github.com/XKNX/xknx/issues/89 ).

Maybe, this issue has another source, and not the exception we see now. Maybe this exception is the result of an different issue…

Hi,

i have the same issue with HA 0.62.1 used in docker with https://hub.docker.com/r/homeassistant/raspberrypi3-homeassistant/ image

The "error" seems to appear randomly after a few hours/days of running HA. When it happens the log file size crashed the docker image ...

any hints appreciated!

[Julius2342]

Another question: does this problem arise directly after starting HASS? Or does it happen when hass was running for a while?

[firefrei]

It happens when hass is running for a while

[janitza-bjag]

It seems that 0.62.1 is more stable according to this issue, it is running for 5 days now ...

@janitza-bjag you found a solution? I guess I have the some issue. After a few hours/days I lost the KNX connection. HA is still running. HA 0.7.4.1

[firefrei]

In my HA setup (0.74.0) the problem also still exists
