SIGSEGV error with Argus JP 5.1.5

carolina.trejos · September 9, 2025, 9:01pm

Hi,

We are working on an GStreamer application in which we capture from 8 IMX390 cameras on a Jetson AGX Xavier. We are trying to migrate to JP 5.1.5 but we are running into the following issue:

Caught SIGSEGV

This issue happens randomly when starting one of the cameras, but can happen with any camera. The pipeline we are using is simply gst-launch-1.0 nvarguscamerasrc sensor-id=$i ! fakesink

We have tested the camera stability with v4l2-ctl and we have no issues with capture there. Have you guys seen this issue at all? Is this a known issue or are there any ways we can avoid it?

Any help will be much appreciated.

Hi @ShaneCCC, thanks for the patches. I tested them on JP 5.1.5 but they don’t seem to fix our issue. In fact, I now see another error:

Do you have any other patches I can test? They can be for either JP 5.1.2 or JP 5.1.5, we have the same issue on both.

ShaneCCC · September 18, 2025, 4:37am

Any script to repo this issue?

carolina.trejos · September 18, 2025, 4:50am

We use the following script:

#!/bin/bash

start_cameras() {
	# Loop for 8 cameras (sensor-id from 0 to 7)
	for i in {0..7}; do
	    echo "Starting pipeline for sensor-id=$i, logging to log$i.txt"
	    # Run the pipeline in the background and redirect output to log files
	    echo "============================" >> log$i.txt
	    date >> log$i.txt
	    GST_DEBUG=2,*argus*:6 gst-launch-1.0 nvarguscamerasrc sensor-id=$i ! perf ! fakesink >> log$i.txt 2>&1 &
	    sleep 5
	done
	echo "All pipelines are running. Logs are being saved to log<i>.txt files."
}

for i in {0..100};do
    start_cameras
    sleep 30
    pkill -2 gst-launch-1.0
    sleep 5
    systemctl restart nvargus-daemon
    sleep 10
done

ShaneCCC · September 18, 2025, 5:03am

I will try on 6 cameras that what I only have.

Could you also verify by 6 cameras.

Thanks

carolina.trejos · October 2, 2025, 5:10am

I’m still able to reproduce this with 6 cameras. The failure rate is overall lower but it still happens.

ShaneCCC · October 2, 2025, 5:36am

Could you modify the sensor driver to set fixed exposure/framerate like make the CID function as dummy function to verify.

Thanks

carolina.trejos · October 14, 2025, 3:21am

Hi @ShaneCCC ,

I modified the driver as instructed, but we are still getting some errors. Do you have any other suggestions?

Thanks

ShaneCCC · October 14, 2025, 4:59am

Get the daemon log.

journalctl -u nvargus-daemon -f

carolina.trejos · October 20, 2025, 2:31pm

Hi @ShaneCCC ,

I’ve attached the log from an iteration that failed with SIGSEGV.

segfault.log (39.6 KB)

ShaneCCC · October 21, 2025, 5:16am

The SIGSEGV could be cause by many time capture error and still try to reconnected.

Does the capture timeout error every times?

carolina.trejos · October 22, 2025, 10:21pm

No, it doesn’t fail every time. If just fails on some iterations, and on JP 5 we don’t see timeouts, just SIGSEGV or DISCONNECTED failures.

ShaneCCC · October 23, 2025, 3:31am

Apply below patch to try.

libnvscf.so.r35.6.close (8.4 MB)

carolina.trejos · October 30, 2025, 2:46pm

Hi @ShaneCCC ,

I still see some SIGSEGV errors, 5% of the times it fails with the error. Any other suggestions? I’ve attached the daemon log as well of one iteration that failed.

single_failure.log (17.2 KB)

ShaneCCC · October 31, 2025, 2:55am

How many cameras for the test.

Could you verify by argus_camera.

carolina.trejos · October 31, 2025, 4:28am

We are testing with 8 cameras. We have tested argus_camera and haven’t seen any issues with it.

ShaneCCC · October 31, 2025, 7:05am

Please help to verify by 6 cameras.

Thanks

carolina.trejos · November 11, 2025, 2:53pm

It can still happen with 6 cameras, although less frequently

ShaneCCC · November 12, 2025, 5:54am

Could you verify by single camera.

Thanks
