IT28600: LINUX INTERNAL STACK UNWINDING DURING ASSERTION FAILURES MAY CAUSE RECURSIVE EXCEPTION FAILURES

APAR status

• Closed as program error.

Error description

• When the server is doing it's stack unwinding, it may cause a
  recursive exception.  It isn't always consistent, it may produce
  an extra frame labeled null on one machine and on a different
  machine it will cause the recursive exception.
  
  In the case of the recursive exception, the MSGPATH file will
  only contain the following:
  
  17:47:12  Recursive Exception - Server exiting
  17:47:12  The Master Daemon Died
  17:47:12  PANIC: Attempting to bring system down
  
  And then in the assertion failure file, it will container the
  register dump and the stack trace and then nothing else.
  
  The extra null frame in a stack would look like this:
  
  0x00000000015d891c (oninit.fix) yield_processor_svp
  0x00000000005eaea9 (oninit.fix) periodic_thread
  0x00000000015af303 (oninit.fix) th_init_initgls
  0x00000000015f6b05 (oninit.fix) startup
  0x0000000000000000 (oninit.fix) (null)
  
  Lastly, onstat -g stk <tid> or onstat -g stk all could also fail
  with changing data structure forced command line termination.
