    CICS attempts to write an HTTP message using an SSL connection.
    DFHSOSE calls DFHDSAT to CHANGE_MODE to an S8 TCB, however
    no sockets are available and the request times out. This
    causes DFHDSAT to return a PURGED response with a reason
    code of TIMED_OUT.
    
    DFHSOSE does not handle this response but instead
    treats it as a severe error. This results in message
    DFHSO0002 being issued and a system dump is taken.

Problem conclusion

  • DFHSOSE has been altered to check for a PURGED response with
    a reason of TIMED_OUT after the DFHDSAT call to CHANGE_MODE.
    In that case DFHSOSE will issue a new message, DFHSO0135, and
    return an response of SOSE_PURGED with a reason of
    SOSE_TIMED_OUT.
    DFHMESOE has been altered to add the new message.
