Error doing job: Exception in callback SerialTransport._read_ready()

Hello,

on my HP EliteDesk 800 G4 Desktop Mini (4KW18EA#ABD, i7-8700 CPU @ 3.20GHz) I use Home Assistant 2022.9.4 in a virtual Proxmox VM (Supervisor 2022.08.6, Operating System 9.0, Frontend 20220907.2 – latest).

As a special hardware device I connected a ConbeeII stick (see https://phoscon.de/de/conbee2) from Dresden Elektronik to a USB 2.0 port.

Since a couple of weeks I receive a massive amount of log messages:

Logger: homeassistant

Error doing job: Exception in callback SerialTransport._read_ready()
Traceback (most recent call last):

    ready, _, _ = select.select([self.fd, self.pipe_abort_read_r], [], [], timeout.time_left())
ValueError: filedescriptor out of range in select()

I already tried to reduce the log messages (see https://github.com/StevenLooman/async_upnp_client/issues/74 by adding the following lines to my configuration:

logger:
  default: warning
  logs:
    async_upnp_client.ssdp: debug
    async_upnp_client.traffic: error
    async_upnp_client.traffic.ssdp: debug

But without any significant changes.

I’d appreciate any helpful advice.

Following, I started to see the same today.

x2. 38Gig logfiles are a surprise.

Exactly same problem on my device,
I am running HomeAssistant on Debian with latest Supervised installation + Conbee 2 USB device + Phoscon.

User.log and Syslog increased twice up to 30 Gb. (Out of disc space) within 2 weeks.

Error in user.log is exactly as in previous post.

Syslog is increasing with several errors for influxdb (removed this from home assistant several month ago) - I’ll review configuration….

Same situation here. Also running Raspi 4 with Conbee 2. Userlog and syslog increases about 1 MB every minute!

Log contains errors messages endlessly repeating:

Hello all,

Hope this helps. I also am using Conbee 2 on a RP4 and using the latest version of HA and had the same issues of a rapidly growing error log. Removing the AddOn Deconz did the trick for me. I have no more errors but still can use the connected devices.

Any news on this one? I have had massive issues with my HA crashing. It turned out to be a disk running full, with just this entry. I would like to keep Deconz to add more devices, so that doesn’t seem like a solution for me to just remove the add-on!?

Hello beskeder,

What I did is remove the deConz add-on. This resulted in a more stable config. I still can use the devices but do not suffer the errors in the logs. Hope this helps. Also adding and monitoring devices is going well,

Getting the same errors in HA 2024.2.0 - Docker container running on Raspberry Pi, ZHA integration and SkyConnect.
