Simply out of memory. RAM or VRAM, whatever method you chose.
Note, incase you are using a 3gb GPU, thats hardly enough to run all included models, some will refuse to run. You can also run into memory problems with bigger cards, I'm using a 6gig card, had a running docker container in the background and thought it didn't use any resources as it was idling, however it was still hogging enough vram to yield a similar message in UVR5
