[PVE-User] Host crashes

[Germain Maurice]

Hello everybody,

Recently i got 3 server crashes. I have a cluster of Proxmox 1.8/1.9 (some have diverged).
They are in a 6 nodes cluster of Proxmox, the VM disks are LV through AoE and i use Coraid SAN storage.

For one of them (Node3), the differences between the other servers (Node2 and Node6) were it was using 2.6.32-6 kernel (ksm module loaded but inactive)
and on the others, 2.6.32-4 kernel was running (ksm module not loaded).
I switched back to 2.6.32-4 kernel, and seemed to be better.

However, a few weeks ago, two hosts of the same cluster running 2.6.32-4 kernel crashed too (Node2 and Node6).

The pictures of the stacktraces i took are visible at http://imgur.com/a/FTfuM .

Is someone have an idea on what could have been occurred ?
Ansmers, questions, all is welcome.

Thanks in advance.
