Hi Prasobh,
It looks like rosnode got an invalid metadata when reading from the hires camera pipe. This is an uncommon issue and should really only occur if the CPU is overloaded and starts throttling the client reading the camera images, eventually overflowing the camera pipe, thus getting out of sync. Additionally, it says that the data pipe disconnected, possibly indicating a problem with voxl-camera-server. If this occurs again, checking the logs with journalctl -u voxl-camera-server may provide some useful information as to what issue may have occurred on the hardware side.
