PM97406: RANDOM U0777 ABENDS IN THE NPF JES (FSS) WRITER

APAR status

• Closed as fixed if next.

Error description

• The Network Print Facility uses a JES FSS capture point
  (EZAPPFS) to retrieve job output that is to be routed to
  printers via TCP/IP connections.  This process may occasionally
  terminate with the following:
  
     EZY6182I  NPFFR    xxxxxxxx FSA POSTED BY JES, ORDID=00000010
     EZY6182I  NPFFR    xxxxxxxx START DEVICE ORDER REFUSED,
               ALREADY UP
     EZY6201E FSA xxxxxxxx ABENDED, USER CODE=0777 REASON=00000000
  
  It is possible for this to begin occurring after some system
  upgrade (z/OS release, new processor).
  

Local fix

• Verify that the NPRO in the JES definition for this writer is 0.
  Non-zero values tend to make this problem more likely to occur.
  
  Monitor for this ABEND preceded by this sequence of messages and
  restart the writer proc when it occurs.
