[CentOS] PolicyKit calls fail from rtkit-daemon

Hi everyone,

I'm having some odd system behavior on two CentOS 7 machines. I suspect
that the trouble is related to polkitd and dbus I think that the following
error message is a key clue, but I'm not sure how to continue
troubleshooting it:.

--------------------------begin log-----------------------
Jul 15 10:00:27 localhost rtkit-daemon[1609]: Warning: PolicyKit call
failed: Did not receive a reply. Possible causes include: the remote
application did not send a reply, the message bus security policy blocked
the reply, the reply timeout expired, or the network connection was broken.
--------------------------end log-----------------------

I can confirm that things seem to temporarily improve by killing polkitd
and letting it be restarted by systemd.  I was getting "out of memory"
errors form polkitd until I increased the stack memory limit

This is all part of various login issues when using the Gnome and
Gnome-classic desktop environments over XRDP. I've temporarily disabled the
GNOME and Gnome-classic environments for my users when sing RDP and set the
default to MATE, since MATE seems to be acting correctly. KDE seems to be
fine as well.

Other pertinent info:
# uname -r
# rpm -q systemd
# rpm -q polkit

Any help or guidance that can be given is appreciated.
