SIGSEGV in Roon Server

Roon Software Discussion Linux

Hi there,

about once a day my Roon Server on Linux crashes with the following log messages:

My setup:

  • Roon Server 1.7
  • Docker base image is Debian 10 Slim
  • Docker runs on Debian 10

If it helps here is my simple Dockerfile:

FROM debian:10-slim

ENV ROON_FILENAME RoonServer_linuxx64.tar.bz2

WORKDIR /app/roon

RUN set -eux; \
    apt-get update; \
    apt-get install -y curl bzip2 libasound2 ffmpeg; \
    curl --progress-bar --location --output "/tmp/${ROON_FILENAME}" "http://download.roonlabs.com/builds/${ROON_FILENAME}"; \
    tar --extract --bzip2 --file "/tmp/${ROON_FILENAME}" --strip-components=1 --directory /app/roon; \
    # Download löschen
    rm -rf /tmp/*

Hi Daniel, thanks very much for the immediate response!

I’m afraid the NetworkManager issue is not really related because my Debian host uses neither uses netplan nor NetworkManager. The other issue seems to affect Ubuntu Desktop.

4

Hi Michael, if you haven’t done so, just configure your server with a static IP. That may be all you need to do.

5

It all may be a problem of the DHCP4 client phoning home to its server… I have configured Ubuntu Server with Network Manager and a static IP, and all is well. My recommendation is to configure a Linux host with static IP, until Roon QA acknowledges and diagnoses the problem and comes up with a different solution.

6

Hum… One of my Ubuntu Server 20.04.1 boxes has a dynamic IP (set by UniFi Dream Machine) but Roon does not fail this way, in fact it stays up until I reboot for other reasons. Maybe the issue is lease duration rather than static vs dynamic?

7

If you are running docker on Debian why can’t you install Roon natively in Debian, docker adds a layer of unnecessary complexity (=problems)

8

My lease was set to 24 hrs. I noticed Roon Server crashes every 2-4 days. Since configuring a static IP there have not been any more SIGSEGV events.

9

Thanks for the input so far!

Maybe it’s important: the ConnectionException sometimes happens without the SIGSEGV. So as far as I can tell there are two issues:

  • a ConnectionException isn’t handled and
  • the Mono runtime may crash

The host IP is set per DHCP but never changes so I don’t believe this could affect the service.

10

Even if it doesn’t change, the DHCP client will renew the lease. For me and some other users, setting a static IP on our Ubuntu servers seems to have remedied the crashes. Trying and configuring a static IP is simple enough.

11

Running Roon Server on Arch with a Unifi USG dishing IP’s. None of the issues described here reaching Roon Server.
