Hello @jdkandersson, I see on the logs that the machines are running kernel 5.15.0-73-generic, can you please first try the jammy kernel currently in -updates (5.15.0-76.83)? If that doesn't solve, I would suggest trying the kernel in -proposed as well (currently 5.15.0-77.84). These kernels carry several fixes from upstream stable updates, so there's a chance the issue has been already fixed.

The github-runner charm is a machine charm that runs on virtual machines. The charm creates a LXD virtual machine inside the juju unit/machine and runs the GitHub self-hosted runner application. The self-hosted runner can be used on GitHub to run GitHub Actions. The deployment of github-runner charm consists of about 15 units/machines (one unit per machine). In the past, we would see about one machine going into “down” state about every 1-3 days. From the openstack hosting the machine, it seems the machine has crashed. The syslog includes the following entry: Jun 8 21:15:58 juju-e4d256-prod-github-runner-66 kernel: [27199.579882] BUG: kernel NULL pointer dereference, address: 0000000000000008 The syslog: https://pastebin.canonical.com/p/gYy3Z9XGkN/ Log on openstack: https://pastebin.canonical.com/p/fbGcmQv9JW/ The deployment of the charm was on the jammy series (22.04). This series uses the Linux kernel 5.15. For the last week, the team has been experimenting with upgrading the kernel to the HWE version which is 5.19. Since then we have not encountered crashes in the virtual machine hosting the juju machine. This mattermost thread includes our team’s discussion of this issue and the reason we decide to upgrade the kernel: https://chat.canonical.com/canonical/pl/h8wrrmcnh3d17dtjmg56zf5pwy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2026229/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
