BUG: soft lockup - CPU stuck

[bill_mustermann]

Hi,

when i go home after work and come back next day my test vm on my proxmox4cluster is frozen with this error message:

[h=3]BUG: soft lockup - CPU stuck for 23s![/h]



what is the cause for this behavior and what can i do against it?

This is realy only for evaluating Proxmox4

- 3 nodes as VMWare Player VMs on a physikal dell optiplex 3010 with i5 and 4GB RAM.
- each node has 1 GB and 1 CPU core
- the vm on proxmox has 1GB and one core

i think it is because of the very very very poor RAM and CPU of the 3 nodes, but im not sure. perhaps someone has another idea?

regards,

I have some periodically problem at:
Intel(R) Xeon(R) CPU E5-1650 v3 @ 3.50GHz
and
Intel(R) Xeon(R) CPU E3-1231 v3 @ 3.40GHz

???

very very very poor RAM can for sure triggers this behaviour, for instance when the kernel flushes its page cache, or when doing a live backup
