Memeory leak when sending a new dbus signal

[Priya Raghavendra]

Hi,

What we noticed on our application is that every time we create a new signal and send it, the memory utilization by the dbus-deamon increases, the application memory utilization is almost the same.

We are running this create signal is a loop and we see an exponential increase in memory utilization in the daemon, for e.x. from few kb to about 10MB!

Thanks,
Priya

Yes we are using this iterator when we receive a signal. I have just taken out the main steps from our code and sent it.



You think there is a problem when using this iterator?

-- No no, I just thought it that the reason for leak. In the above code snippet, I am unable to find the reason for leak, and you are not leaking the memory for any string argument, because we need to free them by our self?

Hi,



    DBusMessage *msg;

    DBusMessageIter args;



    /* create a signal & check for errors */

    msg = dbus_message_new_signal(ObjectName, // object name of the signal

                                  InterfaceName, // interface name of the signal

                                  MessageName); // name of the signal



    if (NULL == msg)

    {

        fprintf(stderr, "Message Null\n");

    }

    dbus_message_iter_init(msg, &args);

 --- Are you using this iterator?



    // send the message and flush the connection

    if (!dbus_connection_send(conn, msg, &serial))

    {

        fprintf(stderr, "Out Of Memory!\n");

        exit(1);

    }

    dbus_connection_flush(conn);

    dbus_message_unref(msg);
