In the bin directory of Virtuoso, use the command
nohup ./virtuoso-t -fd +configfile /usr/local/virtuoso-opensource/var/lib/virtuoso/db/virtuoso.ini &
to start Virtuoso. After a period of time, Virtuoso will automatically shut down.

I want to know what caused the Virtuoso service to automatically stop
I hope the Virtuoso service can run continuously without shutting down
Virtuoso can run continuously for years, if its host environment does not shut down or reboot.
The Server received signal 1 message usually goes along with closure of a terminal session where you’re running it in foreground (-f). I suggest you try running it in a screen session that will persist when you close your terminal session. For instance —
screen -S {some-screen-name}virtuoso +configfile {path-to}/virtuoso.ini -fdctrl+a+dto exitscreen
For further Virtuoso-specific support, I recommend posting to the OpenLink Community Forum or the Virtuoso Open Source project on GitHub. (ObDislaimer: OpenLink Software makes Virtuoso, and employs me.)
