Segmentation fault when running the update command

[Maher4Ever]

Hello,

I've been diagnosing an issue on multiple devices in our balena fleet that have been stuck in the Online (Heartbeat only) status after flashing them with balenaOS version 2.95.12+rev1. They have been stuck in this state for a day now. The issue didn't appear related to network connectivity as the logs from the devices were being streamed to balenaCloud. I also went through the steps for diagnosing firewall issues but there were no issues there.

After checking multiple services, I narrowed the issue down to the os-config service which was stuck in a crash loop:

root@48998eb:~# journalctl --follow -n 300 -u os-config

When I tried to manually run the os-config update command I got the same error (i.e., segmentation fault):

root@48998eb:~# os-config update
Fetching service configuration from https://api.balena-cloud.com/os/v1/config...
Segmentation fault

Did something change in what's returned by https://api.balena-cloud.com/os/v1/config that is now causing the crash? Any help is appreciated.
