That is indicating that HG is running those programs on a timer of some kind most likely. I have similar events in my activity logs. If you don't have a timer then that might be different, but I don't believe it's an issue.
EDIT: After looking again, I see that these events are firing every 10 seconds or so. If you want them to run less often you would have to change your timer to a longer duration. If there is no timer (which I'm not seeing in the code you posted), it is most likely triggering off the "When.ModuleParameterChanged( (module, parameter) => " statement.
