PM87425: DFHIS1015 UNABLE TO ACCEPT CONNECTION FOR IPCONN XXXX. IPCONN CLIENT SESSION STATE IS INVALID.

APAR status

• Closed as returned (APAR cannot be resolved without additional info from IBM or customer.)

Error description

• You noticed DFHIS1015 messages after a region stalled due to
  CPU contraints on the LPAR. After the CPU constraint was
  relieved, it was found that IPCONN autoinstall was effected and
  the autoinstallled ipconns were unusable.
  From review of the logs and recreate, it looks like the CTG
  daemon initates a request to connect to CICS. The first
  capability_exchange request comes into CICS and CISS task is
  invoked URM to autoinstall and create the IPCONN. After this
  CISS sends the first capability_exchange to the CTG side.
  During this time, the CICS region is stalled due to CPU
  constaints. CICS SO domain does a socket send with good
  response but CTG side timeout before it reads the first capex
  response from CICS.
  CISS continues its process after first capability_exchange
  response is sent and issues DFHIS2001 message from WEB
  SESSION1. Just after that, session_closed notified from CTG
  comes into CICS, but CISR ignores it. The IPCONN is then set to
  ACQUIRED status but really no capability exchange was
  established fully.

Comments

• This APAR is being closed with a code of RET/AU. This closing
  indicates that the Change Team has been unable to diagnose the
  root cause of the problem using the available system dump and
  job logs.
  
  To ensure that only high quality fixes are distributed to all
  Customers, we require every fix to be fully diagnosed.  This
  will minimize any exposure to a possible PTF error which could
  later be more detrimental to the Customer.
  
  To fully diagnose this problem the Change Team would need to
  see a system dump taken on the first DFHIS1015 message and the
  associated full CICS job log.  The dump must have the CICS
  internal trace active with a trace table size of at least 4MB
  and a minimum of the IS, SO and WB components set to 1.  The
  IS, SO and WB components set to 1-2 and all other components
  set to 1 would be preferred.
