Issue Plesk not reporting memory/swap usage

[Daveo]

Server operating system version

Debian 12.11

Plesk version and microupdate number

18.0.69

Plesk isn't reporting memory or swap usage.



The free command doesn't work in SSH/CLI either, getting free: Unable to create meminfo structure

swapon -s works and shows the 3x 12GB swap partitions (Total: 36G).

Any ideas on how to fix ?

Sounds like: #1072831 - getting memory info fails when running under lxc - Debian Bug report logs

Which has recently been fixed, but might not have found it's way upstream. You could wait it out or you could try to apply the fix manually.

How do I fix manually?

Can't make much sense of the linked bug report.

 

[Daveo]

Also, I'm running Debian 12 on a bare metal server not a VPS.

Any update on how to manually fix this issue please, as I can't make much sense of what's been linked.

@Kaspar how do I apply the fix manually, as having trouble understanding what you linked in your reply.

 

[Daveo]

Tried to fix myself with procps-4.0.4-8_amd64.deb file but it failed and had to revert back to procps 4.0.2-3.

Can someone please explain how I manually fix this, as the fixed version of procps (4.0.4-8) is not yet in the main branch for Debian 12.

Did you also upgraded from Debian 11 to 12? Or did you freshly install Deb 12 on the server? I am not sure if the issue is related to the one in the bug report if you are running a bare metal server. As the bug report only mentions containerized environments being affected. Even though the error in the bug report is similar to yours and there aren't any other issue's/reports I can find with the same error. But it might be.

As for fixing the issue manually, I am not sure to be honest. In the bug report downgrading to a previous version of procps gets mentioned. I'd be hesitant to try that on a production server.

If nobody else has any suggestions, you might want to conciser open a ticket with Plesk support. Maybe they can suggest a solution, even if it's not a Plesk related issue.

I upgraded from Debian 11 to 12 almost six months ago.

How long does Debian take to move stuff from testing branch to main branch (as the procps 4.0.4-8 was put into testing branch back in April 2025) ?

I don't have my Plesk licences directly from Plesk. Purchased them from an authorised reseller (cpLicence).

Our team might not be able to address this particular issue. It might be better to consult with a System Administrator.

I've just rebooted the server and memory & swap usage is now being reported again in Plesk.

Also, the free command now works.

No update to procps yet, still v4.0.2-3.

Weird.
