Segmentation fault in running pipeline with yolov3 AGX

kd637 · April 8, 2021, 7:02am

•Hardware Platform : Jetson
•DeepStream Version 5.0
•JetPack Version 4.4 [L4T 32.4.3]
•TensorRT Version 7.1.3
•Issue Type(question/bugs)
Using deepstream-test5 with yolov3 that is bundled with DS over 5 RTSP cameras is throwing a segmentation fault after pipeline ran for some time. It goes something like:

What can be the possible causes for this?

No clue in your description.

kd637 · April 8, 2021, 8:10am

updated, lmk if it helps

Fiona.Chen · April 8, 2021, 8:31am

Where did you got the yolov3 models? Are you running the case as described in /opt/nvidia/deepstream/deepstream-5.1/sources/objectDetector_Yolo/README?

kd637 · April 8, 2021, 8:38am

Yes. Same. Just within deepstream-test5 and 5 rtsp sources.

Fiona.Chen · April 9, 2021, 3:01am

Can you send us your deepstream-test5 config file and yolov3 nvinfer config file?

kd637 · April 9, 2021, 6:40am

config_infer_primary_yoloV3.txt (3.4 KB) test.txt (8.1 KB)
Here are the files. Here’s some more info: I tried clearing gstreamer cache. There are other processes running on the AGX too: 5 python processes, kafka broker and mongod. Mongo’s dbpath is set to an external SDcard but its mounted inside the deepstream-test5 folder.

Still having the same issue:

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

I have run the case for 2 hours. It works well. Can you provide a stable reproduce method?

kd637 · May 18, 2021, 10:01am

We switched to a new AGX and the problem was solved. I’m guessing it was due to rtsp connection issue from the source with the previous device because recently I ran into a test video(mp4) that gave segmentation fault. So, it should be the consequence of bad data that was produced in earlier. Thank you for your support, you do great work.
