I masked systemd-oomd.service because I have real swap, and when
something starts using too much memory, it starts using that swap and
I notice the slowdown in the system. Then I can do something about
it.
If I understand the situation correctly (which I may not} in my system
this happens: All real and virtual memory is allocated (The system has
16 Gb RAM + 32 Gb Swap.), but more memory is needed, at which point oomd
starts killing processes. The system often becomes quite slow, with a
lot of disk activity, before processes start to die.
Cures might be more RAM, more swap, or cutting the system load. More
swap is probably a bad idea, since the system already appears to be
running slow on account of a lot of swapping.
