Error description

  • A LIBERTY task is KILL'ed at a critical point in its processing
and at this point, the task will get pulled back onto the QR
TCB (from a T8 TCB which has by now been terminated). Error
processing code is driven and attempts to reference an SJKE
field which is addressed by SJKE_PTR.  SJKE_PTR is null it is
only valid for a T8 TCB (which has now gone) and the 0c4 occurs.

****************************************************************
A Liberty task is terminated using the KILL command.  The task
will attempt to unwind its calling stack and in doing so, is
transferred to the QR TCB.  Control ends up in DFHSJJS which
usually runs on the T8 TCB.  If the T8 TCB has gone then any
reference to sjke_ptr may 0C4.

Problem conclusion


    

  • UI66042 UI66045 UI66041

The offending code has been modified and will now only be
driven if there is an sjke_ptr.
