After the last update the game can no longer save after about 3 cycles. It states that there is a free space problem, this is in fact incorrect, as there is almost 100gb free. The logs tell me that there are to many open files. I restarted the game and put a watch on the game pid with watch -n1 "lsof -p <pid> | wc l" and I could see the open file count going up every couple of seconds and never decreasing.

ps. .log extension is nog accepted as file tpe for log file upload.
Start the game and play for 3 cycles, wait for autosave, observe dialog stating an IOException occured during save.
