We’re hitting a reproducible nvargus-daemon deadlock on JP 6.2.2 (L4T r36.5.0, R36 REVISION 5.0) with 7–8 concurrent ZED-X camera streams via nvarguscamerasrc on AGX Orin. The daemon wedges without crashing - accept() still runs on the control socket, systemd sees a healthy unit, but all capture se…

hello willzeng, let’s keep using Topic 372530 for following up.

hello aadiaadi12345, let me have confirmation, is it related to number of cameras? for instance, can you reproduce the same issue with 6-cam setup?

Hey I was able to reproduce the same error with a 6 camera test setup.

we would like to reproduce the same on Jetson AGX Orin developer kit with 6-cam reference board. could you please share your test steps for reference, for instance, did you reproduce the issue by putting 6-cam preview free running? or.. there’s background service running to have deadlock issue hap…

So our test setup was closer to 6-cam preview free running i.e. opened 6 camera sessions which were streamed using gstreamer nvarguscamerasrc. Every stream is an nvarguscamerasrc element. The sessions are opened ones when pipeline starts and held for the life time of the process. Besides that we jus…

hello aadiaadi12345, just an FYI, we’ve tested 6-cam preview, and it’s confirmed they’re running gracefully after 18-hour. so.. is this long run issue? may I know how long you took to reproduce the issue.

hello, I got the syncpoint error within 6-7hrs of running the test. Here is a sample test script I used if that helps. Let me know if you see if something is off in the script itself. I used it to reproduce the issue. fusa_repro.zip (5.2 KB)

hello aadiaadi12345, please have another test with Argus sample app, argus_camera_jpeg. you may try running with six instances for testing. $ export DISPLAY=:0 $ ./argus_camera_jpeg --sid 0 --cap-time 648000 --disable-jpg --xpos 50 --ypos 50 & ./argus_camera_jpeg --sid 1 --cap-time 648000 --disab…

Hey, I ran a few more tests and here are some findings to continue investigation: The stock examples (both one camera per process or multiple cameras in one process) worked fine without any issues. Zed’s gstreamer plugin GitHub - stereolabs/zed-gstreamer: Package of GStreamer elements to inter…

hello aadiaadi12345, please give it a try with this patch for nvarguscamerasrc plugin. for instance, nvarguscamerasrc.patch (2.6 KB)

i tried the patch but no luck. now instead of whole pipeline going down, individual cameras go down gradually instead until all cameras are down.
