Hi,

I've a custom script to get depth of items as soon as they enter ROI . On executing the script OAKD gets disconnected after 2-3 minutes. We tried the depthai-python example script, rgb_depth_aligned.py and it throws same error but after 15 to 20 mins.

Error -
rgb_depth_aligned.py: The device has already been disconnected

We get Device not available on running any OAKD script post that.
lsusb | grep 03e7 command still shows that OAKD is connected.

HOST System Information:

Intel I7 12Gen
NVIDIA A6000
Ubuntu 20.04
DepthAI Version used- 2.15.2.0
DepthAI Repo tag - 2.15.2.0

Camera Model:

OAK-D

Segmentation fault (Address not mapped to object [0x2c9])

The issue looks similar to a one of the comments in forum.

Could anyone please assist me here to figure out the issue ?
