[rules-users] OutOfMemoryError using 6.0.1

I've converted some NurseRostering rules, which worked in Drools 5.50, to OptaPlanner 6.0.1. While it works far better for the time it runs, it uses up whatever memory I can give it (9GB) and then eventually crashes the GUI. with: Exception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: GC overhead limit exceeded Is there a way to limit how much memory OptaPlanner uses? Or is it likely that I'm just adding fact to the WorkingMemory in a way that wasn't a problem in 5.5 but is a problem in 6.0? -- View this message in context: http://drools.46999.n3.nabble.com/OutOfMemoryError-using-6-0-1-tp4028183....
