Memory leaks, poor memory management in B121 and B122

Ok here is hard proof you totally broker memory management in SQX builds > 120.

SQ B120 mem at 50 proc WFA:

Memory usage and WFA progress at 50% using B120

SQ B120 mem at 90 proc WFA:

Memory usage and WFA progress at 90% using B120

SQ B122 mem at 19 proc WFA:

Memory usage and WFA progress at 19% using B122 (also true for B121)

SQ B122 mem at 19 proc WFA crash:

Memory crash B122

can you attach the strategy and project config?

there can be multiple things that could cause this.

I deleted all of them but for now I just added RAM to my systems.

so it seems it was related to RAM - maybe it wasn't configured properly. In the future please attach your strategy and project config otherwise we cannot reproduce it.
