rtems_semaphore_obtain error

Sorry for misinformation , but I now see that the condition 
:CORE_MUTEX_STATUS_CEILING_VIOLATED will result in the Internal error.  
So my real question is, does anyone have any tips for tracking this 
down? I have (obviously) had much experience with the semaphore handler.
thanks
