ANSWERED Stopping an airvpn Eddie Systemd Service

[iboutin 0]

Hi.

I am using this systemd unit file  to start eddie-ui. It's working well at the startup of my server. But sometime, i  want to stop it to make some tests. So, I stop it with a "systemctl stop airvpn.service". A kil SIGTERM signal is sent by systemd to the eddie to stop it, but it don't close gracefully, some errors are generated. Often after a stop, my server can't access the network, I can't restart Eddie and I have to reboot my server. There is a way another way stop an running eddie-ui batch process other than sending a SIGTERM signal? 

Thanks

There is le log of what happening whene systemd stop my service : (i'm running on Unbutu 18)

Hm. Maybe a signal change will do? Try adding the following to the service file:

KillSignal=SIGINT

It's the same as CTRL-C-ing a foreground process in a terminal. As far as I remember, Eddie always exited gracefully. Unfortunately I can't test it right now because 2.19.1 doesn't launch on Linux as of today.

It's working... eddie-ui terminated gracefully with the KillSignal=SIGINT.

Thanks
