Hi,

I thought this problem had gone away and was caused by rdesktop but it
had returned albeit intermittently.

I could try and remove applications one by one (my amateurish but
logical way) starting with the ones I suspect such as Skype (spit).

But I would like to do it with a more professional approach!

The symptoms are:

about 2/3 through shutdown (text) it stops for 1 minute 30 seconds with
something like "A stop job is running for session 1 user peter", with
animated "red stars".

I assume this is a default time set to shutdown processes?

I did find some info on getting journlctl to output a log of what was
happening at the latest time (will try to find again) but is there a
simple way to determine what is causing the problem?

Can I assume that anything from the OS repositories would be fixed
fairly quickly, and its likely to be something like
Skype/VirtualBox/mariadb that would be the cause.

FYI running Fedora 23 64bit and nothing in dmesg - but its working OK atm!

Regards

Peter H

Hello Peter,

whilst skype is a terrible program it won't be stopping your shutdown
process as it never runs with enough to privileges to do that. The
systemd message suggests it is a program you have run yourself from
terminal session. My guess is virtualbox or mariadb. journalctl
-boot=-1 shows logs from the last boot.

Cheers
Amias

It was set to 340mb. Currently using 18mb. Set max to 1024! See if it helps.

Excellent tip, thank you. Just to note it looks like you should run it
sudo -- is that right?
