possible resource leak in capacity scheduler

i have simple 2 node cluster. one node with 2 GB and second with 1 GB RAM

on node with 1 GB is running application master - no memory left, 
nothing runs on node with 2 GB RAM

current application do not runs, it has only AM started and no resources 
for running mapper. If you take a look at screenshot from scheduler, 
interesting is that memory total is cluster metrics is just 1 GB.

Which version are you running? Can you enabled debug logging for RM and see what's happening?

updating to trunk fixed this, or at least i can not reproduce it anymore.
