System programmer response

Usually this problem occurs when data is either coming in faster than the application can receive it or the application is not issuing RECEIVEs.
  • Ensure that sessions with this application have proper pacing counts.
  • Verify that the application is not having a problem that is preventing it from issuing RECEIVEs.
  • If you cannot determine the cause of the problem from the output provided, take the following actions:
    • If you have access to IBMLink, search for known problems with similar symptoms. If no applicable matches are found, report the problem to IBM® by using the Electronic Technical Report (ETR) option on IBMLink.
    • If you do not have access to IBMLink, report the problem to the IBM software support center. Provide the information in the output from the DISPLAY STORUSE command.
