I started a yum upgrade process. When it reached 342/784 (@avahi)

During F20->F21 upgrade I had to run along something like
while sleep 1;do killall systemctl;done
(the real command was longer) as many %post scripts tried to restart
their
daemon but during the upgrade each systemctl command was timing out
with very
long delay.
I had that as well - the cause is that systemd asserts and goes into
panic mode which means it no longer responds to systemctl calls. It
didn't happen to all my machines but it did to a couple of them.
The evidence to look for to see if you are hitting this problem is
messages in the journal like this:
Dec 05 09:08:21 gosford.compton.nu systemd[1]: Assertion 'path' failed
at ../src/shared/cgroup-util.c:913, function cg_is_empty_recursive().
Aborting.
Dec 05 09:08:21 gosford.compton.nu systemd[1]: Caught <ABRT>, dumped
core as pid 3376.
along with a core.XXXX file in the root directory.
