Virtual machine is eating my memory / stuck on reboot

[Sjaak69]

I have a virtual machine which is stock debian 9.2 with docker installed on it (nothing else). The machine runs fine, after a while the proxmox stats show that the machine is almost using all the assigned memory (8Gb):



If I check memory usage inside the machine I see this:


When I return to console i'm seeing a bunch of errors:


When I try to reboot the system, it's stuck and cpu usage spins to approx. 100%

In your host, do an

qm list

to obtain id of your VM
and then

qm config <VMID> (you had to change <VMID> to the real id number of your vm)
