You should update, your version is very old - current is

Code:
root@pve4-test ~ > pveversion
pve-manager/4.2-17/e1400248 (running kernel: 4.4.15-1-pve)

I remember, there was a problem concerning this strange swap problem a while ago.
 
hm.. apt-get not see upgrade
Code:
root@pve:~# apt-get update
