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.
