DeepStream 6.0.1 Triton GRPC memory leak

Accelerated Computing Intelligent Video Analytics DeepStream SDK
1

• Hardware Platform (Jetson / GPU) : GPU
• DeepStream Version: 6.0.1 (nvcr.io/nvidia/deepstream:6.0.1-triton)
• TensorRT Version: 8.0.1
• NVIDIA GPU Driver Version: 470.82.00
• Issue Type: Bug, host memory leak
• How to reproduce the issue ?

I have tested the issue with the RTSP in-out Python sample. The backend is TensorRT. Running the sample with the default inference configuration files does not seem to leak memory, but replacing the nvinferserver configuration with settings that use a standalone Triton server instance and GRPC seems to leak memory consistently, proportionally to the input sources count/resolution/bitrate. The Python process is the one that leaks, so it doesn’t seem like a issue in Triton’s server side. The leak being proportional to the input size might indicate the nvinferserver grpc client isn’t correctly freeing frames, or is buffering indefinitely (does it even buffer/queue?). I have only tested the issue by running the standalone Triton server on the same machine as the DeepStream app, and I used YOLOv4 for the grpc test. Updating Triton server to r22.04 had no effect on the leak.

The Dockerfile and nvinferserver configuration I’ve used are as follows:

Hi @g-ogawa
do you mean you have an DS python application which are based on

and the nvinferserver config?

From your dockerfile, seems it’s not enough to get these setup, could you share a complete setup?

Thanks!

Hello @mchi, thanks for the response.

While my final application is different, I have observed the leak using the linked application (deepstream-rtsp-in-rtsp-out) as is, without modifications aside from setting the nvinferserver config to one that uses grpc and YOLOv4, and yes, that is also the repository I used to compile the post processing plugin for YOLOv4.

Right now I only have a retrained model converted that I cannot publish, but if needed I can convert the publicly available YOLOv4 model and tweak the dockerfile so it’s easier to run the leaky experiment, would that help?

5

yes, any repo of the memory leak you found is helpful.

Thanks!

I’ve made a simple script that runs the Triton instance and the deepstream-rtsp-in-rtsp-out app, and a Dockerfile to build an image that runs that script. Due to the model size I couldn’t attach it here, so I made it available on this Google Drive link. Please let me know when it’s downloaded so I can take it down.

I’ve included instructions on how to run it, but it should be enough to just build the image and run a container. The rtsp source needs to be provided, though the app will work with file:// inputs as well, so I suppose a sufficiently long video could be used instead.

I have included here the container memory usage when running the app for 30 minutes with a 1080p 10fps 4000 kb/s h264 input RTSP stream.

image (2)
image (2)1369×2054 106 KB

While this level of memory increase for one stream is tolerable, we’d like to run quite a few streams constantly on a system that won’t be restarted too often, so a constant memory usage increase would be a problem.

Got issue when tritonserver loading your model,
can you run the model properly?

It seems you have edited the Triton command to be more verbose but in doing so accidentally changed the repository path from /workspace/triton_server to /workspace/triton_server/main_model, and so Triton is trying to read the version ‘1’ folder as a model folder, could you verify that?

My output is as follows:


 docker run --gpus all -it --rm --name=memtest dstest

It should not be related with this option --verbose-log
I verified without this option, also observed same error.
It seems that we should provide the engine file, since the engine you provided is not applicable for us, hence met the error. can you observe the memory leak issue with builtin model Primary_Detector resnet10.caffemodel?

I have made a compute capability 7.5 engine available here, I could also provide the ONNX model if necessary.
I haven’t tried using other models.

13

UNAVAILABLE: Invalid argument: model ‘main_model_0_0_gpu0’, tensor ‘confs’: the model expects 3 dimensions (shape [1,16128,80]) but the model configuration specifies 3 dimensions (an initial batch dimension because max_batch_size > 0 followed by the explicit tensor shape, making complete shape [-1,16128,2])

if i change
dims: [16128, 2]
to
dims: [16128, 80]
loading model failure gone, but got another issue.

I apologize, it seems I used the incorrect ONNX file to build the engine when using a different environment. I have updated the file at the same link and put up the ONNX model here, just in case.

15

It run well finally.
but i can not get memory leak. i used script from DeepStream SDK FAQ - Intelligent Video Analytics / DeepStream SDK - NVIDIA Developer Forums to check HW & SW Memory log.
Can you specicy how you check memory status?

I check by verifying how much memory the docker container as a whole is using, with a RTSP stream as input so I can check over a long period of time, the results for about one hour of running are attached in stats.txt, and memory usage increases over time.

Above log getting from script nvmemstat.py which is for Jetson. sorry about that, we can ignore Hardware memory, just see VmRSS, which is for SW memory, it constantly unchanged during the test. i captured the GPU memory also running the test again, as attached, from the log, you can see the memory will increase to 3926 in around 10 seconds, then it constantly stay at this value.
NOTE: there one another process occupying 2081M, so GPU memory taken by i run is around 1845Mb.

I have tried using nvmemstat and with a RTSP input, it’s only a few minutes of data but VmRSS is trending upwards. I have had no issues with GPU memory, it’s only the overall host memory usage that keeps increasing. I’m not sure anymore if the issue is using Triton/GRPC or if it’s the RTSP input though, since you don’t seem to observe memory usage increase with the sample video file, although it might just be too short to notice any issue, as the memory usage increase doesn’t seem to be constant, i.e. not for every frame.

edit: on a separate note, I’ve updated my actual application to DeepStream 6.1 but it didn’t seem to improve things.

I setup one rtspstream, but i still can not get memory leak, but i just run around 6 minutes, is that enough?

20

In my tests it should be enough time to see some change in VmRSS. Is that the correct process? The amount of memory used looks very different from my logs, when I ran nvmemstat with -p all there were multiple processes that contained “python3 deepstream_test1_rtsp_in_rtsp_out.py” in the name, but only one was the actual Python process.

21

Oh, i used start_test.py. sorry, should be deepstream_test1_rtsp_in_rtsp_out.py

Host memory leak was not only with tritonserver, but also with nvinfer. need to dig into which component or if the app caused the mem leak.

this is log after change nvinferserver to nvinfer:

Thank you for verifying, at least this means it’s not an issue with my environment.

I have also noticed that it’s not completely because of Triton, but switching to nvinfer seemed to lower the leak amount for my custom application. With nvinferserver + grpc it leaked about 200mb/5 minutes for 8 parallel processes, but with nvinfer it got down to about 200mb/2 hours.

In the end I couldn’t pinpoint the exact cause, so I’ll probably end up restarting the application container once a day, but if Nvidia could find a fix or workaround it’d be greatly appreciated.
