[Jetson AGX Xavier] IMX334 x4 cameras - NvCapture Error "Free request list is empty" during continuous streaming

Hi, Nvidia

When capturing video streams from 4 IMX334 cameras continuously on Jetson AGX Xavier,
the capture process fails with error “(NvCapture) Error InvalidState: Free request
list is empty!”, causing all camera streams to stop. Restarting nvargus-daemon
temporarily resolves the issue, but the error recurs after some time.

## Hardware Configuration

- **Platform**: NVIDIA Jetson AGX Xavier (16GB)

- **Camera Sensor**: IMX334 x 4

## Software Environment

- **L4T Version**: 32.7.4 (nvidia-l4t-core: 32.7.4-20230608211515)

- **Kernel Version**: 4.9.337-tegra

Argus api error like this:

hello yann.wang,

may I double check your test commands to launch multiple camera.
please also narrow down by using v4l2 IOCTL for testing these 4 camera streams.
see-also Applications Using V4L2 IOCTL Directly.

Hello, Jerry

Thanks for your reply.

We’re using our own application, built based on the demo 13_multi_camera, to test the issue. We can do the test with V4L2 next week.

Hello, Jerry

I have been testing with Argus-camera for about two days and couldn’t reproduce the issue. Are there any potential reasons that could cause this problem?

There is no update from you for a period, assuming this is not an issue anymore.
Hence, we are closing this topic. If need further support, please open a new one.
Thanks ~1217

hello yann.wang,

did you meant it’s the failure reproduced with your own application only?
