Actually i found another oops which is very similar to the previous one.
Here, vserver is not involved, and the problem starts at drbd which 
lives in kernel space (the other oops started at ocfs2).

Both ocfs2 and drbd make heavy use of network I/O so i guess the problem 
is something in the network layer.

Anything i can do to help to debugging and solving this issue ?

Thanks
Max
