Karamba+Galapagos eat RAM

I have a problem with optimization of construction.
I'm optimize the girder, but galapagos always eat my RAM.

I have long worked with Galapagos and Karamba, but never see something like this.
In my other scripts with Galapagos and Karamba isn't overflow RAM, only in this script

There is one feature, when I stop Galapagos, RAM isn't emptied. It emptied only when I close Rhino.

When I use annealing algorithm, I have the same overflow.

So, I can't optimise my girder.

Somebody, Help Me!

Maybe I have some strange error in my script?

P.S. For opening my scripts you also need Kangaroo.
