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.

It’s going to be hard to help here. Things you can check:

  • Launch Blender from the command line with -d option and attach as text file here any error printed out in the console (do not paste it directly in comment).
  • Check your RAM usage (using your task manager e.g., Note that such big file may require *huge* chunks of memory, which the system might not be able to provide, even when it seems to still have free memory (due to fragmentation…).

Closing due to no response in a long time. Feel free to re-open if you still have the issue, and follow mont's suggestions.

Another thing I would mention is maybe you're just running out of disk space! ;)
