Full root issue
I have seem some posts regarding the full root issue. How can I check the state of my root and how do I avoid running into the issue?

You can download the system logs and open the volume.log file with a text editor. Scroll down until you see something like this:
=== df -h === Filesystem Size Used Avail Use% Mounted on udev 10M 4.0K 10M 1% /dev /dev/md0 4.0G 560M 2.9G 17% / tmpfs 1.9G 0 1.9G 0% /dev/shm tmpfs 1.9G 2.8M 1.9G 1% /run tmpfs 960M 7.5M 953M 1% /run/lock tmpfs 1.9G 0 1.9G 0% /sys/fs/cgroup /dev/md127 11T 4.6T 6.4T 42% /data /dev/md127 11T 4.6T 6.4T 42% /home /dev/md127 11T 4.6T 6.4T 42% /apps
/dev/md0 is the root file system. It should have plenty of free space (< 50% used, and I've never seen ours hit even 20%, but we don't run many apps either).

Well mine is at 52%. Is this a bad thing?

My system is at 19%.
52% isn't great, and suggests you've installed some apps that are using OS partition space. However, it isn't dangerously full, so I don't see immediate concerns.

I have netstat NT running. I also have Logitech Media Server and ReadyNas Surveillance installed but they are not running.

Normally apps are installed to the data volume, which is mounted as /apps in the OS partition. I'm guessing that some of your apps aren't installed that way, and that explains the 52%.
One trick that often works is to move app folders that are in the OS partition to the data partition, and then replace the original folder with a soft link.
But as I said, 52% isn't dangerously full, just at a level where you should monitor it. My pro (running 4.2.x firmware) is at 48%, due to the way I installed crashplan. I could reduce it, but it is stable so I just keep an eye on it.
