Hi Jiusheng,

As Kingsley indicates to run the Virtuoso Server in background mode you simply remove the -df options you were passing and it runs in background mode by default.

The signal 1 messages resulting in the quick shutdown are the only occasions the log indicates the server had been shutdown. When you were running in foreground mode were the terminal sessions the server was running in held open at all times as if they were being closed down after a period of time if the sessions were running on a remote machine that was then shutdown, this would result in the Virtuoso server being shutdown also and may account for the unexpected shutdowns of the server ?

Best Regards
Hugh Williams

Hi Hugh,

we started server instance like this:
virtuoso -df -c <ini file path>

virtuoso -c <config-file>

Note: virtuoso -? will show all the options.

Kingsley

is it more safe to make it run on background? like:
nohup virtuoso -df -c <ini file path> > log 2>&1 &

    Hi Jiusheng,

Looking the the log provided the only shutdown type messages I see
    out of the ordinary today are of the form:

    16:35:28 INFO: Checkpoint made, log reused
    16:52:55 INFO: Server received signal 1
    16:52:55 INFO: Initiating quick shutdown
    16:52:55 INFO: Server shutdown complete

Where the "signal 1" message is normally the result of the server
    having been started on foreground mode (-f) from a terminal
    session and then being shutdown with a Ctrl C from the command
    line. Can you confirm this is how you have been running the
    Virtuoso Server ?

    Best Regards
