Mosquitto: SIGSEGV on start after update to 6.4.1

[chatziko]

Describe the issue you are experiencing

After upgrading to 6.4.1 mosquitto was constantly crashing on start with the following error:

2024-05-28 22:37:39: Warning: Mosquitto should not be run as root/administrator.

My config:

logins: []
require_certificate: false
certfile: local-chained.crt
keyfile: local.key
customize:
  active: false
  folder: mosquitto

The problem disapeared after downgrading to 6.4.0 via a backup. No time to dig deeper at this moment, I had to revert to a stable system.

Please let us know if you figure out the root cause.

For reference there wasn't any code changes in 6.4.1, only a configuration setting

After update from 6.4.0 to 6.4.1 all my Zigbee devices got unavailable, then rebooted HA two times to finally find out that mosquitto was not properly started. Downgraded to 6.4.0 solved the issue. Unfortunately, I have not taken any screenshot from the log but the CLI interface was full with some kind of pipe error messages.

[mawi2684]

I'm still on Core 2024.5.4, OS 12.1 as I've not seen changes in latest releases affecting my setup so I omitted updates on them. In the log I only could find a not very helpful message: 2024-05-30 16:36:18.995 ERROR (MainThread) [homeassistant.components.mqtt.client] Failed to connect to MQTT server due to exception: [Errno -5] Name has no usable address

This looks similar to https://github.com/eclipse/mosquitto/issues/1419 but that was mentioned as fixed in 1.6.8

[bdraco]

If you can get a core dump, it would be great if you could submit an issue at https://github.com/eclipse/mosquitto/issues/new as this is something that will need to be fixed upstream
