i have a strange thing with ROS 3.0rcx (3.0rc8 already in testing: same thing) on all RB133 which i've tested.
If i give a look on /system resource, i can see a strange CPU 100% usage.
Actually, thre's no load on that RB133, but i can see 1%-100%-3%-1%-100%-1%-100% and so on, at 1sec interval.
With the same board, but with ROS 2.9.4x, i can see 1%-2%-5%-2%-3%-1% and so on, at 1sec interval.
Someone know why this happens?
