Created attachment 23382 [details] another similar oops 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 ?

Created attachment 23383 [details] another trace Here it is another trace, triggered by postfix while doing heavy I/O on another server. This time drbd and ocfs2 are not involved.
