"Your system has run out of application memory" ???

[usagora]

This is odd. Got this warning message on my Mac Mini after the weekend when it was literally just sitting there doing nothing (at least nothing user-generated). NEVER got this message before on any Mac I've ever owned and I've run far more apps than this at the same time without issue (including on this very Mac). I closed all apps and restarted since it had been a while since my last restart. The Activity Monitor screenshot was from just before restarting. Will report back if the message pops up again. I didn't actually use the computer before restarting, so I don't know if there were any actual issues or not.

From the second image, probably just quitting Chrome would have solved the problem. Those (Renderer)s can get out of control sometimes

It's just strange how it was never an issue before (at least, I never got this message before). I use Chrome constantly.

Enable 'view all processes' in Activity Monitor. Probably notorious MacOS WindowServer memory leak.

Try to turn off your Mac if You don't need it anymore (like bedtime, etc.)

And don't leave Mac with lots of apps opened in Sleep mode (disable it as well as auto screen lock if not using).

I've been running Mac desktops 24/7 for almost 20 years with no issue (I just put the display to sleep).

And let it be so for the future.
Maybe it's my bad luck.
Or maybe it's because there're different apps on systems.
Or maybe I'm having some flashbacks from my experience with previous macOS/Windows bugs and dodgy moments

Thanks. Based on what others have pointed out, it's probably some anomaly with Chrome that triggered this. I've never had an issue running lots of apps simultaneously and have over 50% free disk space.
