Hi,

i'm using mobicents RTP to implements a media server and SBC monitor, by setting up a call and sending and receiving RTP. Unfortunately, whenever the call is stopped and restarted there is a Thread leak, memory leak and slowly increasing CPU usage, to the point that eventually the app crashes.

I've based it on the RTPChannelTest class.

the call setup is as follows:

    sendSource = new Sine(scheduler);
    sendSource.setFrequency(100);        

    // set peer on sending channel. receiving channel has already been bound
    getSendChannel().setPeer(new InetSocketAddress(mediaServerAddress, sendRemotePort));

    getSendChannel().setFormatMap(AVProfile.audio);
    getRecvChannel().setFormatMap(AVProfile.audio);

    // setup an audio component to receive the input
    sendComponent=new AudioComponent(1);
    sendComponent.addInput(sendSource.getAudioInput());
    sendComponent.updateMode(true,true);

    // setup an audio mixer to receive the input; mix the send component and send channel
    sendAudioMixer=new AudioMixer(scheduler);
    sendAudioMixer.addComponent(sendComponent);
    sendAudioMixer.addComponent(getSendChannel().getAudioComponent());

and the tear down:

        sendSource.deactivate();
        sendChannel.close();
        recvChannel.close();
        sendAudioMixer.stop();
        udpManager.stop();
        scheduler.stop();

the problem appears to be in the Scheduler class, specifically the CriticalWorkerThread and the Worker thread where they remain in the WAITING state on the take statement (line 413) in

                try
                {
                    current=waitingTasks.take();
                }
                catch(Exception ex)
                {

                }                   

the Scheduler.stop() method only sets the 'active' boolean for the threads which can never be tested while the threads are in the WAITING state.

What is the correct way to stop the scheduler to prevent this thread leak?

I've thought of adding something to interrupt the threads, but there is an empty catch block which would just swallow the resultant interrupt.

Any guidance would be much appreciated as this is it makes my head hurt trying to get to grips with this code and how to fix my app or modify the code.

thanks, Mitchell

I've fixed the resource leaks. Let me know if you're interested in them. I can push my branch if you like.

hey Henrique,

sorry, been swamped here. I was planning on waiting until you had
completed issue #23, as you suggested, before doing the merge. I just
checked it's status, and see that it is still open. Is that still the
recommended course of action?

Sure, take your time.
You can pull the master and apply the fix, the issue 23 will NOT impact the Scheduler, UdpManager nor the PortManager.

Thanks

hi mcacker,
how to fix leak resourse ? can you show me?

mcacker commented Jun 2, 2016

I would use the latest branch. The offending class has been completely refactored since I patched it. I can't verify that it no longer has a resource leak as i'm still using my older patched version. If you're stuck on that version for some reason, you can find my patch at #24

Hi Mcracker ,
i have been write a test with MGCP driver ,
When i'm using 100 TPS connection to MMS server. I see in the MSS server , RAM increment very big but not decrements RAM when connection release (DLCX). This is my class test. Can you help me about how to fix it ? or idea because to long time i can't fixed it!

Hi Mcracker ,
this is my test result with 100 TPS , but when application is stop , the RAM still increment , all end point is stop , do you have any ided about this task !
