      Description

      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).
