Realsense D435 Issue
Hello,
My customer has been seeing these issue with the following hardware settings:
- IPC model: Vecow Industrial PC SPC-5600A (Core i7) https://www.vecow.com/dispUploadBox/PJ-VECOW/Files/5048.pdf
- Camera model: Intel Realsense D435
- USB model: 3.1 A-C Dual Screw Black Newnex Black 5m 2.0 #U3S1A01C12-050 https://www.newnex.com/usb-type-c-cables-legacy.php
- AMR1: 1x D435 connected to IPC USB port type: 2.0; 1x D435 connected to IPC USB port type: 3.2
- AMR2: 2x D435 connected to IPC USB port type: 3.2
Ubuntu 18.04.5
Kernel 4.15.0-112-generic
RealSense ROS v2.3.2
LibRealSense v2.50.0
Device FW version: 05.13.00.50
The issues that they are seeing are:
- 100% hang if loading the DefaultPreset_D435.json file.
- Occasionally (less than 10%) not able to get data from D435 after a stop-start.
- Occasionally Ubuntu OS freeze (less than 10%) after a stop-start.
- Occasionally hang when start camera node in ROS function.
Please advise on this .

If your customer is having problems with the DefaultPreset_D435.json visual preset file then they could try launching the RealSense Viewer program and selecting the 'Default' preset instead of the default 'Custom'. They can then export the Default configuration as a new custom json file using the json save option on the options toolbar adjacent to the preset selection drop-down and attempt loading the newly created json back in.
In regard to the performance issues, if the customer is using exotic industrial computing hardware then they may experience improved stability if the librealsense SDK is built from source code with CMake using the RSUSB backend installation method detailed in the link below.

The RSUSB build is not dependent on Linux versions or kernel versions and does not require patching and so can be a helpful installation option for computing configurations that differ from a typical retail computer.
