Short description of error
Blender keeps crashing when I save my file. The file is quite large (600 MB) and uses intensive amount of particles (5 million+ polygons). Whenever I try to save, it crashes. But, if I 'Save As' it saves and then 'Save' works fine for some time. And after some time, the problem recurs.
Exact steps for others to reproduce the error
I couldn't attach the file since its too large.
