Memory Leak in RPi 3 with kodi 17.6

koven · August 8, 2018 at 8:21 PM

Hi

I've been looking for in internet and here in the forum info about how to set up LibreElec for running on a RPi 3.

I've configured advancedsettings.xml file like this

Code

<advancedsettings>
    <network>
        <curlclienttimeout>45</curlclienttimeout>
    </network>
    <cache>
        <buffermode>1</buffermode>
        <readfactor>4.0</readfactor>
        <memorysize>0</memorysize>
    </cache>
    <gui>
        <algorithmdirtyregions>3</algorithmdirtyregions>
        <nofliptimeout>0</nofliptimeout>
    </gui>
    <videoscanners>
        <ignoreerrors>true</ignoreerrors>
    </videoscanners>
</advancedsettings>

I've been looking for errors in kodi.log but I haven't found anything related to this issue.

I've been monitoring CPU & MEM Usage and the only problem I found was that process kodi.bin is taking more and more memory resources as you can see in this top output.

Code

It's taking 85% just before crashing.

Checking top output just after restarting RPi3 you can see that it only takes 17% aprox.

I don't know if I'm missing a best practices wiki or something similar.

Thanks

Kodi 17 is EOL. No more builds or fixes will be released for it.

Try LE 8.90.003 Alpha with Kodi 18 Leia and see if the problem regresses.

Also get rid of ANY Kodi banned repositories/addons from your setup. You won't get any support when those are installed.

Thank you I'm downloading LibreELEC (Leia) v8.90.003 ALPHA – LibreELEC the version you told me to update.

I'll give it a try and I'll let you know

I updated LE and now it's working much better.

Anyway I followed this link to free some cache memory

How to Clear RAM Memory Cache, Buffer and Swap Space on Linux

As you can see it works really good, it's up to you if you want to configure some crontab task.
