    Unhandled Exception - Segmentation error

      Hi all...
      I'm not sure this is the correct place to post this, so feel free to move it if it's not.
      I'm running RSA75(Java 6) on a Windows 7 64 bit machine and I have an application
      that was built mostly in AWT, some Swing. I've been seeing this error for a while now,
      but only intermittently. I got a new machine the other day and now it's happening all the
      time. Here is the output I get.

      Unhandled exception

      I've downloaded IBM's support assistant and have been able to analyze it to a degree, but nothing jumps out at me as being problematic.
      I'm at a loss. I know segmentation error means physical memory is a problem, but I've bumped up virtual memory on the Win system.
      Not sure what else to do. Does anyone have any advice?
      Thanks in advance!

          No it doesn't. It is a virtual memory problem. It means the application has used an address that isn't mapped into the process's address space, i.e. a wild pointer value or a major array index out of bounds issue. It is a VM bug. Report it to the Bug Parade or as shown in the dump.
