Crashes, and out of memory message in logs

Help and Support Raspberry Pi
1

I would like some pointers as to where to report the crashes I experienced.
If more information is needed, please let me know.

Updated to latest OSMC; running on Pi.

uname -a: Linux mediaplayer 4.9.29-13-osmc #1 SMP PREEMPT Thu Dec 21 17:18:07 UTC 2017 armv7l GNU/Linux

I experienced some crashes since.

In the logs I see:

kernel: Out of memory: Kill process 2268 (kodi.bin) score 845 or sacrifice child

but I am not experienced enough to know what this means or what to do to solve this problem, and whether or not it is actually related to the crashes. I suspect the crashes are possibly caused by an add-on but I don’t know how to triage that either. (sorry :frowning:)

Is this something OSMC-related, do you think?

The device is running low on free memory

Thanks, @sam_nazarko, for the quick reply!

I found some commands which show available memory, and ran free en cat /proc/meminfo. If I am interpreting this correctly (am I?) it seems there’s 454 Mb available.
Does that confirm your diagnosis?

I ran:

osmc@mediaplayer:~$ free --mega
              total        used        free      shared  buff/cache   available
Mem:            765         136         454          15         175         575
Swap:             0           0           0

Correct. The free command shows 454 MB free, but that’s after the oom-killer has killed kodi.bin. This also suggests that kodi.bin was very likely to have been the memory hog.

You might find that the out-of-memory problem is related to one or more “greedy” Kodi add-ons, assuming you’ve installed some. You should be able to disable add-ons one at a time to see if/when the problem disappears.

Alternatively, it could be an application that you’ve installed that is the issue.

Thanks @dillthedog, I have learned something :slight_smile:!

I suspect it can only be one particular add-on: I only have 2 installed AFAIK, and only really use one of these (Dutch iPlayer), and was using just that one, when the crashes occurred.

Thanks.
I’ll report to the add-on developer.

I’d recommend you get some further concrete information before going to the developer. One occurrence is insufficient evidence. Also ensure that the other add-on is disabled, so you can reasonably point out that it’s the only active add-on you have.

Thanks!

Will do as you advice.
I think I’m pretty certain I’m able to reproduce the crash, but can’t at the moment test that, because somebody is using OSMC at the moment and doesn’t want to relinquish the remote just now. :smile:

((BTW: Tell Sam to get some sleep :wink: .))

Try capturing full logs when you experience the problem again.

I get plenty of sleep.
