[SOLVED] Memory leak when idle?

[grandcanyon]

I am running Xbian on a Rpi 3+ and Kodi will freeze and I see in dmesg that I get an out of memory error. I don't get a kernel panic. Kodi restarts but the previous screen stays on the TV so I can see it happens at random times.

PRETTY_NAME="XBian 11.0 - Bullseye"
NAME=XBian
VERSION_ID=11.0
VERSION="XBian 11.0 - Bullseye"
ID=raspbian
ID_LIKE=debian
ANSI_COLOR="1;31"
uname = 6.1.28+
getconf LONG_BIT = 32

I don't see any memory leak warnings in the kodi.log file. I do run iptvsimple so I don't know if this is a source of my problem or something else.

I thought it could be this but it was already disabled sudo echo 0 > /sys/kernel/mm/lru_gen/enabled

Any pointers?

Are you running a heavy skin?

No just the default Kodi skin Estuary is all I use. I don't have any other skins installed besides the two default ones.

I created a swapfile at /var/swapfile so now Kodi doesn't freeze or cause OOM_killer to kill Kodi. Looks like upstart zram-swap should create the swapfile but it doesn't. I believe it is due to the file system being btrfs. The upstart log doesn't give any info for zram-swap except /proc/self/fd/9: 43: echo: echo: I/O error

I have the same problem. As workaround i just increased the swap partition to 1.5GiB (default was 256MiB (?) or something like that).
Now Kodi does not crash or restarts.

I do notice that Swap usage can reach up to 700MB sometimes, and only a Kodi stop/start clears the swap back to zero.

If you don't see any memory leak warnings in the kodi.log file. But it does run iptvsimple, so I think it is because of other reasons. It should be that there is something wrong with the system when you restart. I suggest shutting down again and then turning it on again later.chatgpt login

My system wasn't creating any swap (0 GB) which was causing my problems. I created a swap but I was still getting some crashes and dmesg gave me an error about can't swap pagenets or something on a non-sub volume. I had to create a swap on a subvolume. Since then no crashes.

The first step in fixing the memory leak problem with Kodi on your Raspberry Pi 3+ running Xbian is to use `top` or `htop` to monitor memory usage and see if any processes, such as `iptvsimple`, are using excessive amounts of memory. Make sure there is enough swap space, look for problems in the Kodi logs, and turn off the `iptvsimple` addon for a while to see whether the problem still exists. Last but not least, upgrade Kodi and your Xbian system to the most recent versions. You may also want to tweak Kodi's RAM and video cache settings to enhance performance.
