Every run writes an errorLog. If you have just killed a failed run, there will be an errorLog in the directory mentioned here.
The reason you are having to do this is that Java is running out of memory and you’re restarting without having fixed the problem. Doing this over and over is user error, not a bug.
The errorLog will tell us what the max heap that Java was started with actually was; if we have that, we can suggest what you should do next.
