Data set is to large, but what possible things could be creating? Is there a certain place I would be looking?

sorry can not help too much. I haven't seen this when I use proc lifetest. one guess is that, when you use plots, survival is an internally used variable and it conflicts with your variable 'survival'. try rename your survival variable, or toggle with not using plot, and see if the message is gone. I am curious at this so it will be great if you can share your results. thanks!

Hmm. I tried this earlier and didn't work.

did you try: 1.replace all 3 variable names of survival, censor and failure and 2.keep the dataset with only these 3 variables?
