Target disk does not have enough free space to write the project file
I have serious problems with my project. Suddenly it started work very slow. I musted use autosave because I couldn't do anything in my project. Finaly I'm working on auto save of auto save. Now I can't save my project because all the time I got this message 
I have 100GB+ of free space on each disk and project disk have 200GB+ of free space..
It's so pathetic because I spent 3 weeks on this project and all the time I have problems with software. This is my last month with Premiere Pro I swear
