Bug#1072831: getting memory info fails when running under lxc

Show all headers | View raw

Package: procps
Version: 2:4.0.2-3
Severity: normal

I am running a number of virtual systems under lxc via libvirt.
This means these systems share the host kernel (not like qemu where a
whole virtual machine is emulated).

I upgraded one to bookworm today, and when running 'ps faxu' or 'free'
I get an error: Unable to create meminfo structure

I downgraded procps to 2:3.3.17-5 (including libprocps8 2:3.3.17-5)
and then it worked again.

Working 'free' output:

# free
               total        used        free      shared  buff/cache   available
Mem:         2097152       64600     1932352        9028      100200     1932352
Swap:       10338296      795392     9542904


Not working 'free' output:

# free

I'm willing to help debug on my system if needed.

Thanks,
