Strange Security report after installing Plex plugin

[Z300M]

My system is as described in my sig.

I installed the Plex plugin yesterday but so far have been unable to access the media from either of my Roku 3 boxes. Then this morning's Security report contains stuff I do not understand:

Code:

​

Do I need to worry about any of this -- especially the "Lost n pages of memory" reports?

What's the driver for the NIC (from ifconfig run from the shell of the FreeNAS system)?

The UMA keg thing appears to be something in the em and igb drivers: https://bugs.freenas.org/issues/4058.
