My first guess would be wine. There are all sorts of leaks in that.

I'm not aware of any memory leak / vm problems with -ck although that may be
possible. However ck4 does not have the OOM killer enabled so it's not that
in action; you simply have run out of memory and it can't allocate any more.
Have you tried without the aa vm addons in ck? Does this happen with vanilla
2.4.20? -ck is a very different branch.
