JR51691: PARALLEL JOBS RUNNING ON WINDOWS REPORT FATAL IOPORT ERRORS

IBM InfoSphere Information Server, Version 11.3.1.2 (Fix Pack 2)

APAR status

• Closed as program error.

Error description

• This problem happens on Information Server 9.1 and later on
  Windows
  systems only.  This is an intermittent failure. Parallel jobs
  will  have  this fatal message in the log:
  APT_IOPort::readBlkVirt: read for block header, partition 0, [fd
  4], returned -1 with errno 10,054 (Unknown error)
  Even though the error is listed as FATAL, the job does not
  abort.
  
  
   APAR JR51661 was created to force a job failure
  when the failure occurred. This APAR covers the root cause of
  the IO error.
