PS4 App Crash - CE-34878-0 - System 4.07, Latest App (17.12.2014)

Hello. I am an IT professional, running a Plex server for my household. I am also a lifetime Plex Pass holder, and avid supporter of the platform.

The PS4 application crashes regularly on my 2 PS4 consoles due to an out-of-memory issue, with the error code CE-34878-0. Both are original edition PS4 consoles, with upgraded HDDs only. The crash can be easily reproduced, and happens when a movie is selected from the main menu (before playback has begun). I would seem this is due to the artwork files or meta-data although “refreshing” this data and manually removing and re-adding the files does not help. I have also tried wiping and resetting the system software, and can reproduce the issue when Plex is the only new software added to the system.

PS4 System Software: 4.07
Plex Server Version: 1.3.4.3285
Plex App: Plex = 2.12.10, PlayStation 4 = 01.40

What is causing this issue? It is very frustrating having the application crash, just because a specific movie or tv show is selected.
