Hi Jeff,

Our contractor, Patrick May, who encountered this problem will
be calling you when he sees it again. He described to me that this
happens when the application reaches a certain size. It is a little
alarming since we are going to have a demo to show how much better it
is to develop in Java next week. We are hoping that this bug won't prove
otherwise if it causes a core dump during our demo.

Maria,

     Here's the stack trace I get when the app core dumps (a couple of times a
day).
