appium-espresso-driver: Server crash with OOM

While trying Espresso on one of our app, on a screens which have a lot of elements in the hierarchy, finding by XPath brings down Espresso server with Out Of Memory. The Xpath was {:xpath=>"//*[@text='Loading...']"}.

Same thing happens when I try to get page source on that screen
