Can a person detect this JACK mistake message?

OK. I start JACK without beginning the JACK web server. I get:

23:09:22.730 Patchbay deactivated.
23:09:22.765 Statistics reset.
Cannot connect to server socket err = No such file or directory
Cannot connect to server socket
jack server is not running or cannot be started
23:09:23.059 ALSA connection graph change.
23:09:23.250 ALSA connection change.

Then I push the 'play' switch.

I get:

23:10:07.865 Startup script...
23:10:07.866 artsshell -q terminate
Cannot connect to server socket err = No such file or directory
Cannot connect to server socket

If I push absolutely nothing, the above read mistake message repeats definitely.

I mounted JACK from databases and also this is what I obtained.
