You can set parameters dynamically:

Code

1. systemctl set-property kodi CPUAccounting=yes
2. systemctl set-property kodi BlockIOAccounting=no
3. systemctl set-property kodi MemoryAccounting=yes
4. systemctl set-property kodi MemoryMax=100M
5. systemctl status kodi

This don't worked too

Because the system partition of LibreELEC is a read-only partition, which is for a good reason. LibreELEC is set up for use as a HTPC environment, it's not meant for the typical tweaking & fiddling IT tinkerer.

You can edit things of you mount the partition as writeable first.

Just know that all edits will be gone with the next LibreELEC downgrade/upgrade.

How can I make it writable? To test this

there.

My hardware is a Raspberry Pi 3b, your is the same?

But this don't interfere in anything, right?

Quote from vpeter

I have the same.

I also clean all settings and start from fresh and still see memory line.

Try adding line

Code

1. DefaultMemoryAccounting=yes

or

Code

1. CPUAccounting = yes
2. MemoryAccounting = yes

After add, CPU: 233ms shows, but memory don't.

systemctl --version

Show this:

Well, then you are using LE 8.2 I assume.

Use LE 9 and you will see this line Or use MemoryLimit=100M argument Because this is supported with systemd 232.

No. I'm in LE 9. Before I use LE 9 I'm was in beta version, so I update via own LE.

You think this has made something wrong?

How can I check which systemd version I'm on?

I tried MemoryLimit=100M argument too, and don't work. Does not show in status.

Do you see Memory line with kodi service?

No. Look:

In which service you are trying to add this?

Jackett

Weird! My .service is like your, but like I said when I do systemctl status it doesn't show Memory: 1.0M (max: 100.0M

like your.

You have made alterations on /etc/systemd/system.conf?

Quote from vpeter

You ad this parameter to one real service file or empty one?

I have added it to tigervnc service and it is in use.

Code

1. systemctl status service.tigervnc -l
2. Main PID: 1000 (sh)
3. Memory: 1.0M
4. CGroup: /system.slice/service.tigervnc.service
6. # add parameter to service and restart
8. systemctl status service.tigervnc -l

I added for a real service.

Can you show your .service to I see how you do?

Quote from vpeter

Memory: 1.0M

When I do systemctl status myservice.service never show this!

I'm testing this How to set limits (ulimit) for services run by systemd in CentOS/RHEL 7 – The Geek Diary

Creating a file in /storage/.config/system.d/myservice.service.d/ulimit.conf and put it inside

Code

1. [Service]
2. MemoryMax=100M

Don't know if it works! But when I was doing a systemctl show myservice.service -p MemoryMax before said MemoryMax=infinity, and after creating this file says MemoryMax=104857600.

Hope it work!

This did not work

/storage/.config/system.d/ allows you to override any of the embedded .service files with your own

How can I make it writable?

So, I want to make changes on system.config. But when I type nano /etc/systemd/system.conf says File '/etc/systemd/system.conf' is unwritable.

I want to make this change because I want to put memory usage limits on some services that I use. I tried added the line MemoryMax=100M in a .service, but does not seem to have any limit on the service. I read a little and people say to edit the system.config to make this changes.

It's possible? If yes: how?

What does --optimize-all do?

I don't know! Here says "it turns on the optimizer flags in Mono". But I don't know what this means.

Quote from thoradia

If you can fix the freeze then submit a pull request at github or post your service.jackett.service here

For sure!

Quote from thoradia

As for the --debug switch in Lidarr, Radarr and Sonarr, what good would it bring?

As for root privileges, everything runs with root privileges in LibreELEC

I searched a little and find this that running with --debug switch only will provide debug informations, rsrsrs (noob here).

It's because I saw a warn and thought something was wrong. Sorry for that!

Quote from thoradia

What changes do you want to make?

I might pick them up if they are pertinent

So... My hardware is RPi 3b. I can run sonarr, radarr, bazarr and transmission without problems. But if a execute jackett, in every rss sync of sonarr/radarr a lot of memory is allocated and not release, and in some point (after some hours) LibreELEC freeze. In this jackett page have a systemd file for low powered system. The change I want to make is this to see if it's an improvement.

Other things that I noticed:

In Sonarr logs always says "Mono is not running with --debug switch". I tried adding --debug in the sonarr service (like this radarr example) but this persists. Before using LibreELEC I used OSMC and added that resolved.

Every time I open the Jacket this warning appears: "Jackett is running with root privileges. You should use Jackett as an unprivileged user."

I also tried a solution. Change the privileges with chown -R with another user / group, but LibreELEC did not allow it.

These warnings do not seem to interfere with performance (not that I've noticed), but are warnings.
