Observations: There were two deadlocks last night, probably caused by infinite loops due to non-synchronized threads in one internal Java function. It's gonna be the subject of the third test for today.
Average CPU load was about 15-20% which is very good [until a deadlock has occured]. It only confirms my theory that BrainKing application is very fast but it occasionally gets jammed because of multithreading and related issues. Good news are that it is not hard to fix, once I know where the problem exactly lies.
