I’m using linux mint 21.3, and a process (brave aka chrome) sometimes memory leaking, so eats all the RAM, and then linux goes into swap death loop, when everything freezes (sometimes the mouse cursor is moving), and nothing can’t be done, i can just see the HDD led blinking, and do a reset. Is there a way to make the system automatically detect swap death loop, and close the biggest ram user process, and so on?
Unfortunately, there is no guarantee that the leaking process will be the next process to try to allocate memory after you run out. It might actually be your window manager, for example.
The OOM killer is a last-ditch attempt by the OS to keep running, but it is very likely to leave your system in an unstable state.
