Debian/linux client make "stop job is running" at shutdown/reboot

[vladof 0]

Hello and sorry for my english, so nothing wrong with the client, it work very well on Debian Jessie 8.2, but actually i got a little issue with them;

 

i configured my system to launch the client at the start of my gnome session, they run with the root privilege (save keyring) and network lock active (iptable), so everything work fine excepting when i shutdown or reboot my computer, i got a 90sec delay with the message "A stop job is running for Session 1", i don't get this when i manually close the client BEFORE i shutdown. I'm not a expert but i except a SIGTERM issue with the client or another related process ...

 

For now i just bypass this issue by a simple modification in systemd.conf reducing the delay to 10sec.

 

If any one can help me on that ? thanks
