Description Adam Williamson 2013-11-16 02:16:16 UTC 
In Fedora 20 validation testing, I've noticed quite often my systems - usually virt-manager VMs - are very slow to shut down. It seems to be getting worse: I booted F20 Beta TC5 desktop live image 7 times and got slow shutdown only twice, booted F20 Final TC1 desktop live image multiple times and got slow shutdown every single time.

Either way, whenever the shutdown is slow, if I send systemd debug logs to a serial console so I can see what's going on, it seems to be stuck on:

"A stop job is running for User Manager for 1000"

i.e. /lib/systemd/system/user@.service . Haven't managed to diagnose anything further than that yet.

I see the red asterisks shuttling from side to side next to that message - an indication that job is still ongoing - for about 2 minutes before the system finally shuts down. Nothing else seems to slow down the shutdown process.

log of slow shutdown

Following the instructions at http://freedesktop.org/wiki/Software/systemd/Debugging/ , here's the log of a slow shutdown. Note the initiation of shutdown at 132 and then the long pause before user shutdown fails at 222 - looks like a 90 second timeout.

This seems to be duplicate of bug 1023820.

I think you're right. Thanks.
