Segmentation fault (core dumped) #16

avgeeklucky · 2020-06-16T21:52:06Z

Not entirely sure how to debug this, but rbfeeder keeps restarting due to a Segmentation fault (see Container Output).

I'm running docker community edition version 19.03.9 on Debian stretch with an AMD64 CPU. Container setup using docker-compose 1.24.1.

docker-compose.yaml

version: '2.0'

services:
    rbfeeder:
        image: mikenye/radarbox:latest
        restart: always
        container_name: rbfeeder
        restart: always
        environment:
            - TZ=UTC
            - BEASTHOST=192.168.1.20
            - LAT=52.###
            - LONG=4.###

Hi @avgeeklucky,

Have a read of this comment onwards:

#9 (comment)

Short version is that the rbfeeder code is trying to access a temperature sensor that may not exist on your system (as rbfeeder is really only designed to run on a pi) which causes a segfault.

Unless you can somehow “spoof” this sensor or get it working, without editing the source code for rbfeeder there is t much I can do about this unfortunately.

avgeeklucky · 2020-06-16T23:56:47Z

Have now. Sorry, completely missed that. Had a look into the spoofing option, /sys does not like to be messed with, that's not going to be easy.

Oh well, I'll just let it crash for now.

jayp0 · 2020-09-27T12:12:01Z

It seems docker was failing because it was trying to mkdir mount point to read-only fs.
mount to /sys/class/thermal instead of /sys/class/thermal/thermal_zone0/temp fixed it.

    volumes:
      - ./rb/faketemp:/sys/class/thermal:ro

$ find rb/faketemp/
rb/faketemp/
rb/faketemp/thermal_zone0
rb/faketemp/thermal_zone0/temp
$ cat rb/faketemp/thermal_zone0/temp
24000
