Please add zram support for Vero 4k
thx
What are you doing that would need that much memory? The 4K should have more than enough.
Nothing special, just a big database.

We need to figure out what is using your memory, while you still have about 101M free, that seems low. Mine runs with about 760M free.
Before doing anything, you should turn swap off as that will cause extra wear on the eMMC, possibly leading to an early death of the 4K.
Posting logs may help us see what you have that could be using memory.
Try looking at top to get an idea of what process is using the memory.
If it is the database causing the problem, you might consider switching to a MySQL database.
Hi,
As @bmillham says, it’s quite surprising to see a request for zram when the device has 2GB of memory.
I’ve added ZRAM support as per your request:
It will be in the next update.

Thank you 
I will also investigate if the ram usage is based on an issue, or just normal behaviour under my special circumstances.
I tried a couple of workaround to save memory, but still running out.
zram is not stable. I guess caused of the really old kernel…

Hi,
I suggest you provide some logs:
How to submit a useful support request - General - OSMC
It may shed some light on why you have such high ram usage.
Thanks Tom,.
The issue is not the high ram usage, cause this is just related to massive databases.
3840 movies, 12136 tvshows, 22578 musicvideos and 332844 songs.
Without logs, we have no way to help you further. Please supply them so we can help!

I can think of compressed pages being a problem about a year ago, but you’d need to be on a very old version of OSMC (middle of 2017 IIRC) for this to be an issue.

After long time I gave zram another shot, still crashing
Here is the log…

Please supply full debug logs.
If you tell me how? I cannot upload the log file and I cannot post the full log here, cause of forum limitations.
btw, not sure what you expect from the full dmesgs?
Debian buster and it was Kodi 18 and Kodi 19. However, this has nothing todo with the zram issue. This is a kernel / kernelmodul issue.
I trigger the zram manually via script. Before triggering the script, everything is perfect. Even with swapfile.
As soon script enabled zram and zram starts swapping, kernel crashes.
Testscript:
#!/bin/sh
totalmem=free | grep -e "^Mem:"| awk '{print $2}'
mem=$(( ($totalmem /4 )* 1024))
modprobe zram num_devices=4
#modprobe zram num_devices=2

#echo lz4 >/sys/devices/virtual/block/zram3/comp_algorithm
echo $mem > /sys/block/zram0/disksize
#echo $mem > /sys/block/zram1/disksize
#echo $mem > /sys/block/zram2/disksize

Edit:
OSMC is still on stretch, are you running a non-stock osmc?

Yes I updated to buster for python reasons. But this is not the point!
This is a kernel / kernelmodul issue. The kernel is stock from osmc repo (3.14.29-150-osmc).
Even if I would remove kodi, install xserver and run lxde it would still be a kernel issue.
btw, lz4 is also not available in this “old” kernel version. Is there any progress about the 4.9er kernel? Even if lot’s of backports are added to the 3.14 kernel, the core is still old).
Are the gpu driver available for 4.9? I guess this is usually the showstopper moving to newer kernel versions.
The GPU driver is available for 4.9
It will be released end of Summer.
There is no support for Buster at this time.
Great, then I will postpone my tests till 4.9 is released.
Did you have issues with zram on Stretch? I wouldn’t be surprised if the userland and kernel are coupled

I guess yes, but not sure. That’s too long ago, but why do you think the userland have an impact to this issue? From my perspective it’s clearly kernel related. Of course there is always the possibility on inconsitencies, but I would be really surprised if this is the case.
I can check on stock image as well, but this will take time.
