Java OpenCV SIGSEGV JVM Crash

Android/Java
1

I am working on an application that takes frames from a video then splits it into 4 sections. Those 4 sections are then split further. This all happens on several threads. Once it has useful parts of the video section out it notifies the observers that the file is ready to be detected. Everything works, but after so many submissions to the the detector it starts to Crash JVM. I have absolutely no idea how I can go about fixing this.

I am basically looping through each frame and doing processing then calling this for submitting it to the detector:

detector.addFrame(gameWindow1DecisionFrameData);

Here is my detector:

public class Detection {
    private Mat img;
    private int ID;
    private int networkWidth;
    private int networkHeight;
    private String weightsPath;
    private String modelPath;
    private float minThresh;
    
    public Detection(Mat img, int ID, int networkWidth,int networkHeight, String weightsPath, String modelPath, float minThresh){
        this.img = img;
        this.ID = ID;
        this.networkWidth = networkWidth;
        this.networkHeight = networkHeight;
        this.weightsPath = weightsPath;
        this.modelPath = modelPath;
        this.minThresh = minThresh;
    }
    
    public String Run() throws Exception{
        Net net = Dnn.readNetFromDarknet(modelPath, weightsPath);
        Size sz = new Size(networkWidth, networkHeight);
        Mat blob = Dnn.blobFromImage(img, 0.00392, sz, new Scalar(0), true, false);
        net.setInput(blob);

        List<Mat> result = new ArrayList<>();
        List<String> outBlobNames = getOutputNames(net);      

        net.forward(result, outBlobNames);
        
        
        float confThreshold = minThresh;
        List<Integer> clsIds = new ArrayList<>();
        List<Float> confs = new ArrayList<>();
        List<Rect2d> rects = new ArrayList<>();
        
        for (int i = 0; i < result.size(); ++i)
        {
            // each row is a candidate detection, the 1st 4 numbers are
            // [center_x, center_y, width, height], followed by (N-4) class probabilities
            Mat level = result.get(i);
            for (int j = 0; j < level.rows(); ++j)
            {
                Mat row = level.row(j);
                Mat scores = row.colRange(5, level.cols());
                
                Core.MinMaxLocResult mm = Core.minMaxLoc(scores);
                
                float confidence = (float)mm.maxVal;
                Point classIdPoint = mm.maxLoc;
                if (confidence > confThreshold)
                {
                    int centerX = (int)(row.get(0,0)[0] * img.cols());
                    int centerY = (int)(row.get(0,1)[0] * img.rows());
                    int width   = (int)(row.get(0,2)[0] * img.cols());
                    int height  = (int)(row.get(0,3)[0] * img.rows());
                    int left    = centerX - width  / 2;
                    int top     = centerY - height / 2;

                    clsIds.add((int)classIdPoint.x);
                    confs.add((float)confidence);
                    rects.add(new Rect2d(left,top,width,height));
                }
                
                row.release();
                scores.release();
            }
        }
        // Apply non-maximum suppression procedure.
        float nmsThresh = .50f;
        
        MatOfFloat confidences = new MatOfFloat(Converters.vector_float_to_Mat(confs));
        Rect2d[] boxesArray = rects.toArray(new Rect2d[0]);
        MatOfRect2d bbox = new MatOfRect2d();
        bbox.fromList(rects);
        MatOfInt indices = new MatOfInt();
        Dnn.NMSBoxes(bbox, confidences, confThreshold, nmsThresh, indices);

         
        // Grab Results
        int tempID = -1;
        int [] ind = indices.toArray();  
        float confy = 0;
        int classID = -1;
        for (int i = 0; i < ind.length; ++i)
        {
            int idx = ind[i];
            Rect2d box = boxesArray[idx];
            Imgproc.rectangle(img, box.tl(), box.br(), new Scalar(0,0,255), 2);
            classID = clsIds.get(idx);
            Float confidence = confs.get(idx);
            System.out.println(clsIds.get(idx) + " CONFIDENCE: " + confidence);
            confy = confidence;
        }
        
        
        
        return classID + "," + confy;
    
    }
    
    
     private List<String> getOutputNames(Net net) {
        List<String> names = new ArrayList<>();

        List<Integer> outLayers = net.getUnconnectedOutLayers().toList();
        List<String> layersNames = net.getLayerNames();

        outLayers.forEach((item) -> names.add(layersNames.get(item - 1)));
        
        return names;
    }

the detector is called every 100ms by:

private void submitDetection(FrameData frame){
        if (frame.getObject() == null)
        {
            return;
        }
        
        switch(frame.getObjectID())
        {
            case -10://Decision
                System.out.println("Submitting Decision 1 for Detection");
                detectDescision(frame, .80f);
                break;
            
            case 0://Other section of screen to detect
               
                break;
        }
    }

That calls this:

public void detectDescision(FrameData data, float weight){
        String result = "";
                try
                {
                    Mat test = new BuildImage(data.getObject(), data.getID(),data.getID(), 640, 128).Build().getObject();
                    Detection detector = new Detection(test,0,640,128,"/home/user/nn/UI/UI_best.weights","/home/user/nn/UI/UI.cfg",weight);
                    result = detector.Run();
                    detector = null;
                if (!result.isEmpty())
                {
                    String[] vals = result.split(",");
                   
                    System.out.println(vals[0] + " " + vals[1]);
                    
                    
                }
                }
                catch (Exception e)
                {
                    //Logger.getLogger(CardDetector.class.getName()).log(Level.SEVERE, null, e);
                }
        
        
    }

The video is played at 30fps and updates the observable when a new frame is ready. It does this until there are no more frames in the video left. If I comment out detectDescision(frame, .80f); there is no crash.
