[pve-devel] memory consumption

I'm never see this, maybe it could be a tcmalloc bug not releasing memory.

Is it the kvm process witch use a lot more ram ?

Hi, 



some of my virtual machines on different servers are consuming a lot more ram then they should! 

(up to twice) which is a horror if the machines have about 15-20G but consume 30-40GB 

I was checking: 

) all machines have the same pve packages installed 

) it only happens on machines with ceph osd installed 

) which also are using rbd client for virtual hdds 



It does not happen if they are using nfs backend for virtual hdd. Or other machines which are just using the rbd client but doent have osd’s… 



Has somebody experienced something like this also? 

Any ideas how to debug further?
