Transcoder throwing "Cannot allocate memory" and "Could not find ref with ..."

Server Version#: 1.25.8.5663
Player Version#: Web


Heya!

Trying to convert some of my 4K HDR H265/HEVC media via the “Original Quality” setting, however the Console is constantly throwing the following, at the bottom attached lines over and over again.

One thing that stands out is the “Cannot allocate memory” error, which is weird since my Server has 16GB RAM allocated where the Transcoder uses roughly 3.2GB and in general everything on it (including Plex) uses ~9-10GB. CPU specs are 24 Cores with 2x Intel Xeon E5645.
I may actually be running into the Transcoder’s 32bit application RAM limits here while trying to encode this particular file, from the looks of it. Or do you guys maybe have another guess what this could be?
