No runaway CPU, but I just had ~60 console-kit-daemons leaking after a
day's worth of frequent Capistrano deploys (which launch multiple SSH
sessions) on a brand-new EC2 instance running Ubuntu 12.10. Probably not
your issue, Whit, but the leakiness is still concerning.

Just had a serious runaway console-kit-daemon on Lucid! Ran my load up
into the 40-50 range with 100% CPU. Killall console-kit-daemon reduced

Running `pam-auth-update` allows you to remove using ConsoleKit as a

restarted since (lots of remote cron tasks).
Use of ConsoleKit on a box that gets connected to at a minimum of once a

Added Munin and Monit. Now console-kit-daemon takes over in a couple

Munin does. Makes it happen much faster.

I think you would be able to reproduce it with just slightly more
testing time. 1000 logins probably isn't enough to reveal the problem.
I just do while `true`; do ssh localhost echo '$$'; done and let it run
for an hour, or overnight, and then I believe you'll see it. There's no
special reason
Similarly, I have a headless server that does all its work from cron.
After a while (maybe a week), it's unusable because console-kit-daemon
is taking 99% of the CPU.
Removal seems unwise, as it offers to remove lots of useful packages, so
I suppose the answer is another cron job that kills
I haven't seen this in a wee while, maybe it's because I have started to
shutdown instead of serializing to RAM but I'm not too sure.
Somewhat surprised that a month old server crippling bug is still of
'unknown' importance; in my case it's severe
This is why Debian is still such a good choice
I profiled this piece of junk. Console kit daemon spends more than 94%
of its time in g_slist_find() at the top of this stack:
#0 0xb7f17db9 in IA__g_slist_find (list=0xa164ae0, data=0xa033210)
at /build/buildd/glib2.0-2.18.2/glib/gslist.c:574
#1 0xb800c5a9 in dbus_g_proxy_manager_filter
I get the same, except in the server flavour of Ubuntu.
I'll be sitting here, and every 10-15 minutes, the CPU jumps to 100%,
the fan goes full tilt. I thought it might have been alot of dust, but
after having htop running for a bit, i notice console-kit-daemon is the
culprit.

Ditto for me if I leave the PC/Lap Top on for some time when I return to
it the fan is going full tilt and it's all due to the 'console-kit-dae'

The way I read it, sessions are being leaked into console-kit-daemon,
and every time a session is added or removed console-kit-daemon does
something that's either O(N) or O(N^2) or worse. I'm up to Session
#31399 and every time a session is added or removed, c-k-d eats another
4 or 5 CPU seconds
Here's a really easy way to reproduce this problem. Assuming you have
an ssh keypair which allows you to login on your own machine, do this:
while `true`; do ssh localhost exit; done;
console-kit-daemon will runaway with the CPU eventually.
In my opinion this is a very serious problem for
