'mcu' shutdown: Rescheduled timer in the past

Hello,
I get the following error at irregular intervals

" MCU ‘mcu’ shutdown: Rescheduled timer in the past
This generally occurs when the micro-controller has been
requested to step at a rate higher than it is capable of
obtaining.
Once the underlying issue is corrected, use the
“FIRMWARE_RESTART” command to reset the firmware, reload the
config, and restart the host software.
Printer is shutdown "

Can someone tell me how to fix this?
