Error in real time kernel when I use camera and Flask server

edit

Hello,

I try to run a server Flask on real time Ubuntu kernel for Franka Ros. After a moment the server seems to be stuck.

On my server, I use multiple camera a the kernel seems to be unstable.

Is there a way to modify the following added statement to allow using my server beside Franka Ros contoller?

@realtime soft rtprio 99 @realtime soft priority 99 @realtime soft memlock 102400 @realtime hard rtprio 99 @realtime hard priority 99 @realtime hard memlock 102400

I use Ubuntu 20.04 ans Ros Noetic.
