Every iteration results in a 3.5gb load getting added into ram = pc crashes at fill

[Enferlain]

I set iterations to 10 each, for like 10 images, and after the scoring process and when it starts a new iteration, it adds the I assume model size to the ram. I have 64gb, and it fills in after 10 iterations of warmup, I can't even get to the optimization part.

What should I do to fix this?

mmm weird...
the models should be loaded and unloaded to avoid this behaviour

what's the webui version you are using?

[Enferlain]

My version is 1.6.0 AUTOMATIC1111/stable-diffusion-webui@5ef669d

Maybe this error output has some information, I got it once but I don't remember if subsequent crashes cuz of ram fill had this exact error message

Same issue here, have you ever fixed this @Enferlain ?
