Hello,

One of my proxmox 4.4 hosts became very slow and I'm looking for the reason. CPU and RAM are not specially high but CT are slow. I see these lines every 10 sec in syslog I do not see in other hosts. Can it be the reason of slowness ? What does it means and how to fix it please ? Thx

Restart of pvestatd or the whole server does not change anything.
 
Can it be the reason of slowness ? What does it means
Not likely. It's an informative message about which CPU cores are being assigned to which containers. You can try setting cpulimit instead, if you want to avoid it.

Also, please consider updating to the latest Proxmox version to get the new features and bugfixes!
