Public bug reported:
HP Z400 Workstation
Intel Xeon W3520
12GB RAM
nVidia QuadroFX 580
Kubuntu Trusty 14.04.2 LTS, apt-get says everything is up to date
Kernel 3.13.0-46-generic x64
KDE SC Version 4.13.2
Accountsservice 0.6.35-0ubuntu7.1
My system seems to boot just fine until it tries to bring up LightDM. At
that point, accounts-daemon eats up 100% of a CPU core, starts
allocating tons of memory and causes LightDM to hang for ~25 seconds.
After I put in my username and password accounts-daemon continues eating
up 100% of a CPU core, allocates more memory and hangs the login process
some more. After being logged in for a few minutes it stops using CPU
time but never frees any memory, eventually settling in at ~6GB used. At
the time of this writing it is currently at 5,754,280K.
If I kill the process it frees all of the memory, but after locking the
screen or similiar action something (dbus?) starts it back up again and
the process repeats, although only using up ~3GB of RAM. I have tried
running accounts-daemon --debug and it doesn't spit out anything
indicating an error. The closest that I've found to a problem is in the
lightdm.log file excerpted below:
<snip>

<snip />
dbus does seem to start the service successfully as evidenced in syslog:
<snip>

I'll provide any help that I can, and thanks!
