See my thread here on reloads without restart: https://forums.elementalgame.com/406297
Any user can duplicate this by just reloading games. 100% guarantee it will crash the system eventually, somewhere between loads 13 and 20. They are working on it!
My thoughts: if they can get this nailed down it should help with other OOM issues. Although I doubt this issue is the root cause for all oom issues, it certainly is a root cause completely in SD's control. I'm doing nothing but loading saves - so crazy activity by the user is not a factor (although I am a bit crazy). If they eliminate this gremlin (treat each reload as something comparable to a fresh elemental instance) then any remaining oom crashes are other gremlins that need hunting down. Process of elimination!
