How can it need 2Gb of memory? Drools Planner has 2 solution instances: the bestSolution and the workingSolution.
If you use solutionTabu of for example a 1000, it has a 1000 solution tabu's too. Your options: 1) Better cloning. See Examination: only the examlist is deep cloned, the periodlist, roomlist etc aren't even cloned. 2) Less solutionTabu, use the benchmarker. You're probably better off with a solutionTabu of for example 500 and moveTabu of 7.
