Well, my first guess is that the memory allocated to PHP is being exhausted. Try increasing it. Here’s an excellent blog post on how to do that:

They provide several methods because the method that will work for you depends on the web host. My suggestion is to start at the top of the list and work your way down to see if that resolves the issue.

While you are at it, can you please share a System Info link with me? You can create one on the Connections : Tools admin page under the System Info tab (bottom of page).
