Extremely High Server Load

[stnd]

Since I reinstalled to version 8 every once in a while my server load will go up like crazy and server will become half responsive. Wondering if anyone knows how I could trouble shoot this. CPU usage is not high. Just load.

load average: 160.77, 161.06, 160.83

On one of my LXCs the samba service seems to fail. This was not happening before the upgrade and it is the same LXC and configuration as before. Wonder if that has something to do with it.

Have you checked with top/htop whats causing all the load?

Top works, htop doesnt work, ps aux hangs and doesn't work. I have since restarted the pve node, but really want to figure this out. CPU usage was very low. Somehow the samba server dying has to be connected.

What typically happens when a VM or LXC runs out of memory. Can it affect the whole hypervisor or should only that VM/LXC hang/fail.
