No luck get same memory leak on 1.3.4.3285-b46e0ea as well; a new Plex version was released a few days ago but i also see the memory leak there as well.
No idea how to fix it, perhaps an update will be released eventually that fixes the problem, until then i guess I'll just have to put up with it, adding an extra 8GB has helped as the crash only happens every couple days now. One thing that is better using the Docker, is only the Docker crashes now instead of the entire system when using the Phaze plugin. The docker also seems to automatically restart after a crash so other may have the issue and not even know unless the crash happen when they're watching something.
