Stack overflow - help needed

   Hello,
    OS = Tru64 V5.1A
    One of the user got an error message during the execution of a program:

    stack  overflow
     .
     .
    Core dumped.

   The present configuration:
   sysconfig -q proc  output

   $sysconfig -q proc 
proc:
max_proc_per_user = 256
max_threads_per_user = 1024  
per_proc_stack_size = 4194304   <-------------------
max_per_proc_stack_size = 48000000  <---------------------
per_proc_data_size = 2147483648
max_per_proc_data_size = 2147483648
max_per_proc_address_space = 2147483648
per_proc_address_space = 2147483648

   limit output:
   =============

  $limit

filesize        unlimited
datasize        2097152 kbytes

coredumpsize    unlimited
memoryuse       3068192 kbytes
vmemoryuse      2097152 kbytes
descriptors     4096 

   Can I just increase the process stack values(proc stack and max stack)
   without increasing the other values? What is the maximum size I can
define
   for stack in a 3G memory machine?

    Thanks in advance,
      Kumar
