Update: it just happened again, but this time without any sync being performed 
at all (the sync network between the nodes is physically down at the moment 
to prevent the issue...). The current master node just went down with OOM 
errors, but it had 95% of its 3GB swap partition free at any time. Therefore 
I have to assume that non-swappable memory was consumed until none was left. 
The XEN dom0 instance where drbd is configured currently has 384MB RAM 
assigned, with basically no additional services running (sshd and a slave 

How much is drbd supposed to consume per GB and per volume?
