Yep, came here to say the same and see if others were having the same problem. I’m on an Intel mini, but like others here, it looks like a segfault in the Plex Transcoder process. Oddly, I have a launchctl watchdog to keep an eye on Plex Media Server, but these crashes aren’t being seen as a “crash” by launchctl, so my server isn’t being kickstarted the way it should be.
