[BUG] LE 12 Update via GUI generates a crash (-log)

[eldersixpack13]

Describe the bug

see Bug #7987

LE 12 nightly update from 52b450b to 8b39055, but it happend earlier too

How to reproduce

Steps to reproduce the behavior:

1. update via GUI
2. reboot
3. see: /storage/.kodi/temp/

Information

• LibreELEC Version: LE12
• Hardware Platform: Intel NUC13

Log file

log during update:
kodi_crash.log

log after update:
kodi.log

Context

regarding the logs: I guess the crash happens during the update (see nightly git hashes)

Network => Maximum Wait Time: 5 sec

[antonlacon]

So the steps are: update via gui, and find a kodi crash log in /storage/.kodi/temp? I can't reproduce with an RPi3. I used the November 24 -> November 25 nightly RPi2 builds as in your logs.

Would you try logging in via ssh and running systemctl --no-block reboot and see if it produces a crash log? This is the reboot command being used when the addon performs an update.

[eldersixpack13]

Thanks for looking into it.

"systemctl --no-block reboot" (without quotes) does not produce a crash log.

I'm no developer (just an IT-Monkey (Support, Admin) retired, using ~20 years Linux (Redhat 6.x, Fedora since FC1)
To me it seems /usr/lib/libpython is running wild.

Box was new installed ~3 month ago, LE11, upgrade to LE12, ...

just did a update to 505b95f and with "Network => now with Maximum Wait Time: 10 sec"
=> no crash log

will retest with Maximum Wait Time: 5 sec again and report

[eldersixpack13]

as said tested with Maximum Wait Time: 5 sec

=> crash

@antonlacon

It may not crash if you are going directly to update. I can reproduce the issue by selecting all LE-Settings tabs and then performing the update.

We are using TimeoutStopSec=30 for kodi. On weaker devices this may not be enough time to create a crash log. Consider increasing this value with a systemd drop in file.

You can use the persistent journal setting to look for crashes without log in shutdown e.g.:

Dez 02 11:38:20.768693 marsle12 kernel: LanguageInvoker[1043]: segfault at 6 ip 0000000000000006 sp 00007f56257f9218 error 14 in kodi.bin[400000+1b56000] likely on CPU 2 (core 2, socket 0)
Dez 02 11:38:20.768798 marsle12 kernel: Code: Unable to access opcode bytes at 0xffffffffffffffdc.
Dez 02 11:38:21.355624 marsle12 kodi.sh[1002]: Segmentation fault (core dumped)

---

Finally here is a crash dump of a debug enabled image: kodi_crashlog_20231202113821.log

If you have any idea how to proceed ... ;-)

[antonlacon]

I added a drop-in at /storage/.config/system.d/kodi.service on the December 4 RPi2 nightly image.

[Service]
TimeoutStopSec=60

I can provoke a crash by restarting the Kodi service. Journalctl shows:

Dec 04 03:12:05.077097 LibreELEC systemd[1]: Starting kodi.service...

The error shows up somewhere around 20% of the time. Same error can show up from rebooting the system.

Is this still happening with current nightlies.

[eldersixpack13]

Yes !

[eldersixpack13]

seems to be fixed since nightly (18.01.2024)
Thanks !

[mglae]

It crashes most of the time but not at any update.

Reopening.

[heitbaum]

@mglae - is this still an issue, or did it get fixed in the current LE12b1?

[eldersixpack13]

Still an issue here.
In January I made a wrong assumption after 3 in row without crashlog

[heitbaum]

Status request:
Is this still occurring in LE12 (released)?
Is this occurring in LE13 nightlies?

[eldersixpack13]

yes on LE13 nightly 738b75b

[heitbaum]

@eldersixpack13 are you still experiencing this?

[eldersixpack13]

Yes
