@mikec_pt could I get an update?
Edit: Just as a test, I installed a new clean version of plex and imported a movie that always fails.
Here are the logs (with verbose & debug enabled) for that crash; all server settings are default: (File removed)
Edit 2: I accidentally stumbled upon the fix in this thread: Subtitles not working in Plex 1.18 on FreeBSD/FreeNAS
The solution is setting the “kern.ipc.somaxconn” tunable to something higher than 1024. It was you @mikec_pt who replied in that thread, so thanks for that I guess
