The realtime operating system has been reimplemented, bringing module CPU utilisation down by around 80%. The previous versions had various issues which would show up when exposing port 10001 and sending event reports.
The latest 4.16 build version 2 doesn't suffer from the issues. It's advisable to use the latest or switch to the SelfMon module for classic, G2, G3, Dimension, and Flex V1.
