Comment 9 for bug 1972159

This is greatly exasperated because systemd until v251 is using MemFree and not MemAvailable to decide how much memory is remaining. Since Linux aggressively uses MemFree for caching, this will result in systemd-oomd excessively killing applications.

There's a fix in upstream 030bc91cb98385904b28a839d1e04bb4160a52d2, which was released as v251 about a week ago.
