I solved a very archaic.
immediately after starting the rendering process using encore, I open program management, (cntr + alt + del) and na section control how much memory consuming processes PProHeadless.exe. every time you get to high values break the process encore, he established and then continuously PProheadless PROGRASS in encore
By doing so, PProheadless starts emptying the memory.

Conclusion … not a hardware problem, but of PProeadless who can not manage the memory lock when engaged.

I hope it is understandable translation of google.
