Ubuntu 18.04.2 LTS - Plex Server Crashes - Double free or corruption (!prev)

Thanks to everyone for the help in getting logs that i can match to uploaded crash reports. We have not yet been able to reproduce these crashes in a debug development environment

I have been asked to see if any of you would be able to get a core dump of the crash - preferably on the latest beta. I understand would need to enable core dumps on the system? There is some generic info here: https://linux-audit.com/understand-and-configure-core-dumps-work-on-linux/amp/
