Snapshots me frien el server (Proxmox)

Saludos:

Hace bien poquito contrate uno de los nuevos servidores SP-64 cun una controlada RAID LSI Logic / Symbios Logic MegaRAID SAS 2208 y todos las particiones formateadas en ext3.

Pues bien... cada vez que se lanza un snapshot (da lo mismo que sean programados o manualmente desde el manager de Proxmox), me deja totalmente frito el server. Esto es lo que me escupe el log, además de sacarlo por consola:

Alguien ha tenido alguna experiencia similar? Como lo ha podido solucionar?

He tenido varios servers con Proxmox en OVH y nunca he tenido estos problemas. La unica defirencia es que no tenia controladora RAID asi que creo que el problema viene por ahí.

Cualquier idea o sugerencia será bien recibida.
