PMS (Docker:latest) Segfaults frequently since last update

Plex Media Server Desktops & Laptops
1

Server Version#: plexinc/pms-docker:latest (1.18.2.2058)
Player Version#: N/A

Running latest docker image on UnRaid (+nvidia) 6.8.0, for the past 24h several crashes occurred.
Noticed it, since was watching some x264 1080p content and it stopped abruptly.
Looking at the logs, I found several occurrences of segfaults relating to the PMS daemon.

Update: can confirm that issue seems to have subsided on the latest docker image. No crashes for the last 10days (since i’ve updated to the latest branch).
