Error description

  • A socket file descriptor leak causes the following MQIPT error:
    MQCPE017 The exception java.io.FileNotFoundException:
    /opt/mqipt/bin/../mqipt.conf (Too many open files) was thrown
    causing MQIPT to shut down
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of MQIPT 2.0.0.1 who receive connection requests that
    disconnect without sending any data (such as a network pinger).
    
    Platforms affected:
     All Distributed (iSeries, all Unix and Windows)
    ****************************************************************
    PROBLEM SUMMARY:
    When a connection request to MQIPT disconnected without sending
    any data the socket to the caller was not closed. This left the
    socket in a CLOSE_WAIT state. Not closing these sockets led to
    the FileNotFoundException (Too many open files).
    

Problem conclusion

  • The code is updated to close the socket when a connection
    request to MQIPT disconnects without sending any data.
