Core Dumps

              ********** CORE DUMP SIZE LIMIT **********
  
  When a Unix process you run fails  with a "fault" (memory fault,
  segmentation fault, etc.) the system attempts to create a core dump
  file named "core" in the current directory. However, the file will not
  be created unless your "core dump size limit" is set high enough to
  accomodate the core dump file. Since most users don't want to look at
  core dump files, and because they can consume an annoying amount of
  disk space, each user's core dump size limit is set to zero by default
  and core files will not be created when processes fail. If a user wants
  to get a core dump from a failing program, he must increase his limit
  with the command:
  
        ulimit -c size (ksh)
        unlimit core   (csh, tcsh)
  
  where size is the maximum size allowed for the core dump, measured in
  1K blocks. 
  
  i.e.  ulimit -c 1024         (ksh) 
        limit core 1024        (csh, tcsh) 
  
  would set the core file size to 1 Megabyte
