Running out of Memory

Hello. I’ve got quite a few blogs (thousands). Whenever I try to mass activate, I run out of memory: https://www.otleylogic.com/screenshots/Screen%20Shot%202013-10-27%20at%206.48.58%20AM-CIo757tLi5.png

Is there any way of re-coding the plugin so that it doesn’t do everything at once.. maybe in chunks for better memory management? Even if you can’t code it yourself, maybe you can point me in the right direction and I’ll be able to mod it.

Thank you
