and REASON CODE 000001A0.
Does this indicate a problem?

Environment:  

  • Supported z/OS level
  • CA Common Services r14.1
  • CA CCITCPGW or CCISSLGW

 

Answer: 

z/OS uses an S422 abend as a signal to a thread to terminate.  As long as this does not happen during normal operation it is not a problem. During shutdown, we are issuing pthread_cancel() functions which will result in an S422 abend under the covers.
