Resolution:
You will want to use a symbolic debugger such as gdb (gnu), or dbx (Sun).
Assuming you are using dbx as the debugging tool, do the following:

1. Launch dbx with the command:
        dbx $RTHOME/bin/$RTARCH/rtserver.x  core
where core is the core file produced by the crash.

2. At the dbx prompt, please type in the command 'where'.
        Example: dbx> where
   The stack trace will be displayed on screen.

3. Copy and paste the trace directly to an email and send it to support@tibco.com.
