Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Content Manager on z/OS resource    *
  *                 manager V8.4.3 running under WLM in          *
  *                 scalable mode.                               *
  ****************************************************************
  * PROBLEM DESCRIPTION: When terminating a resource manager     *
  *                      running under the IBM HTTP Server,      *
  *                      itself running under the WLM configured *
  *                      in scalable mode, users will see a user *
  *                      abend U4038. This abend is taken after  *
  *                      shutdown and does not affect            *
  *                      functionality nor reliability. It does, *
  *                      however, cause a delay until the abend  *
  *                      is taken, and it causes the system to   *
  *                      capture the abend itself.               *

  * RECOMMENDATION: APPLY CORRECTIVE SERVICE                     *
  ****************************************************************
  The resource manager was interfering with the termination
  signals used by WLM to communicate its address spaces to shut
  down. Unable to communicate with its address spaces, the WLM
  eventually terminates them and issues the user abend U4038. This
  only happens during the shutdown of a resource manager which is
  running as a scalable WLM application: it does not happen if not
  in scalable mode, and it does not happen during normal operation
  of a resource manager.
  

Problem conclusion

• Content Manager on z/OS resource manager was modified to no
  longer interfere with the specific signals used by WLM to
  communicate its address spaces to shut down.
