    socket is not released.
    

Local fix

  • No workaround, fix required.
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users of CICS TG statistic API programs
    ****************************************************************
    PROBLEM SUMMARY:
    If an attempt to connect to a CICS TG statistics port failed to
    complete, the socket used was not cleaned up properly and was
    not reused. After many attempts to connect to an inactive CICS
    TG statistics API port no more socket descriptors were
    available.
    A statistics API trace will show socket descriptors not being
    reused.
    ****************************************************************
    

Problem conclusion

  • CICS TG has been corrected to release sockets for failed
    connections.
    

Temporary fix
