  ****************************************************************
  CICS Transaction Server was processing the response to an
  application request from CICS Transaction Gateway (CICS TG).
  A Web Session Block (WBS) was updated to include information
  about headers and user data for this response.
  During this processing the CICS mirror task was suspended and
  a PING message was received from CICS TG.
  CICS TS reused the same WBS for the headers for the PONG.
  The mirror task was resumed and the application response
  returned to CICS TG in a corrupted state, leading to the
  CTG8495E message being issued.
  

Problem conclusion

• CICS TS has been changed to serialize the use of the WBS control
  block so a PONG response will not overwrite data for an
  application response.
