How fo free RAM when I switch checkpoints?

[evilblade666]

Hey folks!
I've googled and saw that some people had the exact same problem, but those threads are a year+ old and I never once saw a solution in them.
The problem is I have an old PC here with just 16Gb of RAM. When I firstly generate image - it loads the currently selected checkpoint and I can see that free RAM reduces to something like 6Gb. After that if I continue generating on the same checkpoint - all's fine.
But as soon as I try to change the checkpoint it doesn't unload that previous one from RAM and tries to load the second one into it, wich usually ends up with out-of-RAM situation and PC freezes continuing to actively access the HDD. And no, it doesn't try to put that unused parts of RAM to swap since I don't have a swap at all.. I actually don't know what's it trying to do, TBH.
So.. is there a way to unload current model(s) from RAM other that comletely shutting down the AUTOMATIC1111?

I am also suffering from this problem. Although I have the “Maximum number of checkpoints loaded at the same time” set to 1, why is it running out of RAM when switching checkpoints?

Same here - Maximum number of checkpoints loaded at the same time is 1, then something about checkpoint caching is also set to disabled... in short - everything is pointing-out to that only 1 checkpoint must be loaded in RAM at any time and eyt it isn't :(

I have the exact issue. I can load one with no problem, but loading any others will slow to a crawl. I have to kill A1111, relaunch it and then load a new checkpoint! Even that is faster than switching mid session. Something must have broke.

Yeah, I've pretty much ended up doing the same here. CTRL-C the A1111 and then I've configured my Midnight Commander to launch it with the checkpoint I've pressed enter on.
