Thanks for the answer. Interesting, although I dont really understand everything you said.

Task manager:

Performance page: CPU at 100% Memory up to 4.6Gb

Processes page: PP.exe at 1.3, render64.exe at 1.8

 

I'm afraid I don't know what VIRTUAL MEMORY/PAGE FILE is, I have to find out. Help, please?

 

I have rendered extremely busy scenes with up to 8 V4's with hair, clothes, etc without any problem while shutdown has happened when rendering 1 V4 & 1 M4.

It seems to happen randomly with no logic.

 

Shutdowns occur with or without displacement maps checked.

 

I do indeed use separate process since I read your guide ;-) No change :-(
