Description
The 5 "CAN Send Thread"s are using ~6% (of a single cpu core) each, for a total of 6-8% overall cpu utilization. REV HW client is not active, this is out of the box idling. Motioncore is attached, but no devices are plugged in.

Research direction
Start by reproducing the reported idle setup with Motioncore attached, no devices plugged in, and REV HW Client inactive. Inspect the five CAN Send Threads and compare their CPU use with the report's roughly 6% per thread; done means the unexplained idle utilization is understood and the regression is addressed.
