I did further research and saw indications that these kinds of frame number problems may occur if auto-exposure is enabled.

Could you check please if the hardware timestamp of the frames is also the same, please? This is because Dorodnic the RealSense SDK Manager answered to a user with the problem of repeated frames with the same frame number and HW timestamp:
"This is the expected (or at least possible) behavior. This can happen when one of the streams drops frames (in that case we will return last known frame from that stream). If you are building the SDK from source, please make sure to build with -DCMAKE_BUILD_TYPE=Release You can also try reducing the total resolution".

Thank you very much for comparing the hardware timestamps. The reason that I asked about this is because if the frame number is repeated but the hardware timestamp is different, that is considered to be an abnormal behavior.

Are you recording the data to a file such as a bag, please?

Does the frame number duplication occur less if the resolution is reduced, please?
