Title:
callbackRequestDelay not waiting for 1/60 sec on vxWorks
Status in EPICS Base:
New
Bug description:
The problem is documented in this tech-talk thread:
https://epics.anl.gov/tech-talk/2020/msg00308.php
In 7.0.3.1, but not in 7.0.3, callbackRequestDelay(1/60) results in
100% CPU time, most of the time in cbHigh.
This happens on vxWorks 6.9.4.1 and was first seen with the scaler
record with multiple types of scaler hardware and device support.
