  Pipe open time-out can occur on a system where CPUs are busy.
  The maximum wait time can be changed by coding the PIPEWAIT
  control statement, but the statement does not change the
  maximum wait time of pipe open. The PIPEWAIT control statement
  should be applied to the maximum wait time of pipe open also.
  If a time-out occurs in opening the pipe between the Unload task
  and the Reload task and the Unload task ended but the Reload
  task is running, an abend 0C4 (ABEND0C4) can occur in the Reload
  task.
  

Problem conclusion

• The following modules have been modified so that the PIPEWAIT
  control statement can be applied to the maximum wait time of
  pipe open: HPSGCM00, HPSGTP00
  The following module has been modified to avoid an abend 0C4
  in the Reload task when a pipe open time-out occurs: HPSGTE00

   2.7 Control Statements
    2.7.6 Description of Control Statements for
          Reorganization Manager
     2.7.6.17 PIPEWAIT Control Statement
        PIPEWAIT specifies the amount of time a writer or a reader
     of a pipe can remain in a wait state before IPR Driver issues
     a message and abends.
      _________________________________________________________
     |                                                         |
     | >>__PIPEWAIT__ _(__time__,__pipeID__)_ ______________>< |

     |_________________________________________________________|
  
     The first parameter time specifies how many of minutes, from
     1 to 1440, a writer or a reader, connecting to the pipe that
  |  is specified by the second parameter pipeID, can remain in a
  |  wait state before IPR Driver issues an error message or
  |  messages and gets to an abend. The parameter applies to both
  |  a wait state in opening the pipe and a wait state in getting
  |  a pipe block to write or read. For the valid pipe IDs, see
     "Notes on pipe ID" in topic 2.7.6.15. If pipeID is not
     specified, pipe ID 1 is used for the second parameter.
     The default time value is 15 for each pipe.
