Dylan, please look at the following thread where at least two persons have posted their syslog entries corresponding to the exact same SIGSEGV events @Paul_Hermans is describing.
At the moment of the SIGSEGV Roon quits logging and will come back some ten seconds later when it is up again.
We are all on Ubuntu 20.04.1 LTS. I today reinstalled my Roon core server, using a minimal install of Ubuntu server.
