If this quantity is too small, you might sometime saturate it with when performing memory intensive operations. That’s when you get java.lang.OutOfMemoryError: Java heap space errors. You can explicitly set the amount of memory Ubooquity is allowed to use (be careful to set a value lower than the actual physical memory of your hardware). Value is a number of megabytes ( put just a number, without MB )
