APAR status

  • Closed as program error.

Error description

  • During the close cycle of a TCP connection, the Trading Partner
    does not send a FIN,ACK. This results in the Perimeter Server
    waiting indefinitely in FIN_WAIT2 Status for this FIN,ACK
    signal from the TP.
    

Local fix

  • RTC ID: 574721
    
    
    Preferred solution is to request the TradingPartner to comply
    with the RFC and close connection correctly.
    Alternatively, a restart of the Perimeter Server will free up
    the number of FIN_WAIT2 connections. However, they will build up
    again once new connections are made.
