Before it happens it is working Slower and Slower, each action is taking longer, then it restarts and the strategy needs to be loaded from the last saved file to continue work on it.
It looks like some Memory Leak where more and more memory/resources are consumed until each reaches some trigger to restart.
I have learned to Save my work every few minutes to not loose what I have done.
I am perfectly sure it is not only me who is facing this issue.
Please let me know if you find I can help you somehow to debug this problem. I can i.e. run something in the background to gather data or memory status (whatever is needed).
