On my Ubuntu Core appliance, Frame sometimes receives SIGTERM from the init process:

ubuntu-frame.daemon[15736]: [<timestamp>] < - debug - > mirserver: Handling Terminated from pid=1

I cannot reproduce this reliably yet. I observed both a single automatic restart of the frame daemon service and a completely black screen where I would need to force-restart Frame.

Expected behavior

Ubuntu Frame should stay up and running.

Actual behavior

Ubuntu Frame daemon service restarts, or sometimes halts completely. Error message in ubuntu-frame.daemon log:

ubuntu-frame.daemon[15736]: [<timestamp>] < - debug - > mirserver: Handling Terminated from pid=1

I'm providing as much debug information as possible below in <details> tags to keep this readable 🙂 Based on the debug message, this may also be a better fit for the mir repo, please move it if necessary.

Device / OS setup

Ubuntu Core 22 custom model image on a Raspberry Pi 3B rev 1.2, armhf architecture.

The gadget snap is based on the reference pi-gadget snap (22-armhf branch) and only adds minor modifications to config.txt, two kernel command line parameters and default config / connection for seeded snaps.

The appliance is set up via a WiFi captive portal without an initial internet connection, so the system time is usually way behind until users have configured their WiFi credentials and NTP could sync the correct time.

Hi Tobias, PID 1 is systemd… so something must be causing systemd to try and restart Frame. The obvious candidate would be the snap refreshing, can you see if things in snap changes correlate with when Frame restarts?

or sometimes halts completely

That one's more worrying. Is the error the same when this happens? What's systemctl status snap.ubuntu-frame.daemon say?

this may also be a better fit for the mir repo

No, terminating on receiving SIGTERM is correct behaviour. Any problem lies in not understanding why systemd is sends SIGTERM, nor why snapd doesn't restart Frame after it exits.

Thanks @Saviq @AlanGriffiths for the quick feedback.

can you see if things in snap changes correlate with when Frame restarts?

Service-related things in snap changes do correlate with Frame restarts, but not always. I have to admit it's a bit of a puzzle because the timestamps are off: My appliance needs to reboot once after initialization (i.e. seeding) so that NetworkManager reports the correct connectivity. After the reboot, system time is ~7 minutes behind again because the device didn't get an NTP sync and the RasPi does not have a RTC. So all log entries from the initial boot have “future” timestamps. I guess systemd does not parse previous log entries and hiccup on those, so they should “just” affect log entry order?

That one's more worrying. Is the error the same when this happens? What's systemctl status snap.ubuntu-frame.daemon say?

I have not been able to reproduce this one yet, so I can't provide further details right now. Will update here if I observe this again.

One thing I noticed in the logs:

~$ snap logs -nall ubuntu-frame.daemon | grep -a6 -b1 -i fatal

This only occurred once, but I can't tell if this was during an initial boot (i.e. frame was setting up the first time).

This only occurred once

That looks somewhat like canonical/mir#2799. (But without a stack trace it is hard to be sure if it is the same thing - there might be clues earlier in the log)

I checked my test installations for these log lines, below is the full log from a ubuntu-frame.daemon service start that ended in a fatal error. note the ~2min delay between the last startup log line at 2023-01-19T15:42:58Z (scaling factor) and the Handling Terminated from pid=1, so honestly, I can't remember if I shut down the service myself as part of a system reboot.

Three things I noticed, but don't know if they are relevant. This is on a Raspberry Pi 3B with the config provided in my first post.

  1. The VC4 driver seems weirdly out of date and has no proper version:
2023-01-19T15:42:57Z ubuntu-frame.daemon[15577]: [2023-01-19 15:42:57.270685] <information> gbm-kms: /dev/dri/card0: using driver vc4 [Broadcom VC4 graphics] (version: 0.0.0 driver date: 20140616)
  1. This warning. Could be caused by prevent_firmware_kms_setup enabled in config.txt?

  1. This warning, the attached screen is 1080x1920 and frame proceeds to list supported modes for the connected HDMI-A-1 output.
