That indicates a real time issue on the RPI
Have you run a latency test?

It's going to help if you can describe your system, are you using ethernet, SPI or gpios (software steeping). Mesa, remora or other hardware.
Your HAl & INI files will help as well.

Typically with a RPI4 you need to
set the force_turbo option true (in config.txt)
set isolcpus to 2,3 (in cmdline.txt)
You may also need to lower the servo thread
period to 2ms (2000000)

Change

to
SERVO_PERIOD = 2000000
SERVO_PERIOD = 1000000
to
SERVO_PERIOD = 2000000
