Hello,

Our servers crash after updgrade to 3.2.x kernel. (from 2.6.32)
Only some of the servers fail, various HW (DELL, Intel, SuperMicro).
We use cgroups for mem and cpu hard limit.
We do know if it's HW or kernel or vserver issue...

Kernel log form last crash (3.2.38, SuperMicro):

and config (based on Debian+Beng):

Another crash: http://paste.linux-vserver.org/23333

Maybe I found a similar problem reported by "ard":

Thanks,
