Problem summary


    

  • System crash with following stack when dupmsg called from
a process:

 F1000000C01E06CC pse:dupb+00000C (000000006963E93E  ?? )

 0000386C ovlya_addr_sc_flih_main+00014C ()

    



Problem conclusion


    

  • Code is modified to change dupmsg as kernel service. The
function dupmsg is not exported as system call to the user.
This prevents the system crash.
