Hello, I installed 1.560 the other day and I have seen a few of the following exceptions when building my (rather large) matrix builds:

I have currently given the master over 8GB of Heap Space and the Slaves around the same, but this still happens from time to time. First question, is this running out of memory on the master node or on the slaves? Secondly, should a matrix build with ~15 builds really use this much memory? Should I just up the heap space on the master node until it goes away or is there some code that have recently changed the memory usage?
