[Ubuntu 16.04 (SmartOS)] Plex Media Server crashes while adding a Premium Music
When adding a Premium Music Library, Plex Media Server crashes while scanning the audio files. Adding a Standard Music Library works fine. After the Plex Media Server crashes and restarts, I can "Scan Library Files" and it will continue for a while until it crashes again. Repeating this scan process about 40 times, I was eventually able to add all 725 albums in my music library. I'm concerned about the stability of the system, so I'd like to prevent these crashes.
OS: Ubuntu 16.04 with latest updates running inside a SmartOS LX Branded Zone
Plex Media Server: 220.127.116.1166-fc63598ba
RAM: 8GB allocated to the zone
Attached are the Plex logs and the JSON file I used to create the Ubuntu 16.04 zone (actual domain named changed to "mydomain.com"). After creating the zone, I updated the system (apt get update, apt-get upgrade), configured the hostname and time zone, installed the udev package, rebooted, and finally installed Plex Media Server.
I also tried creating a CentOS 7 zone and the same crash occurs. I installed Ubuntu 16.04 on VMware Fusion 10.1.0 and was able to scan the same music library without crashing. The music library is originally from a Mac running iTunes. The library was copied to a 2010 Mac Pro running Plex Media Server on macOS 10.12.6 under ESXi 6.5 and it worked fine there, too. I tried migrating Plex from that Mac to Ubuntu under SmartOS, and everything came over fine except the Premium Music Library. So, I created this "test" zone to diagnose the problem. I ran the entire music library through FileBot to clean up the naming. I'm using a subset of the library ("Various Artists") for testing.
Can you please help me fix this?
