Sensor keep offline

Hi experts,

We keep getting sensor offline issue while the scan is running, however after we restart the Amp Sensor services, the sensor will back online. Just wanted to know, what could be the reason for sensor to go offline?

This is one of most recent error message I can extract from the sensor log:

Appreciate your advices! Thanks.
