Not only CPU activity:  If the SQE heartbeat on the 10BaseT
transceiver is not on, believe you will also get a high level of disc
I/O, because the system wants to log each of these "events".
When we first switched from 10Base2 to 10BaseT and hooked
up a DTC, we immediately started seeing a continuous 70-80
I/O's per second.  Eventually got around to doing a

LINKCONTROL @; STATUS = ALL

and noticed we had millions of heartbeat losses recorded since
last reset.  Turned on transceiver SQE heartbeat and all was well..
