Segmentation fault in running pipeline with yolov3 AGX

•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:

*** DeepStream: Launched RTSP Streaming at rtsp://localhost:8555/ds-test ***

What can be the possible causes for this?

No clue in your description.

updated, lmk if it helps

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?

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

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

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:
