shutdownvirtuoso

Why does Virtuoso automatically stop running for a period of time after starting in CentOS

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. The information in the log file is,

I want to know what caused the Virtuoso service to automatically stop

I hope the Virtuoso service can run continuously without shutting down

Solution

  • 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 —

    1. screen -S {some-screen-name}
    2. virtuoso +configfile {path-to}/virtuoso.ini -fd
    3. ctrl+a+d to exit screen

    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.)
