What does this actually mean?
I am getting hundreds of log entries for this notice, Is it something I need to address?

Howdy,
I don't see anything too unusual there... it looks like Apache is doing a graceful restart, and in that process, there's some log messages being generated, largely by mod_security. If you want to cut down on the log messages, you may need to configure mod_security to generate fewer messages.
