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 3.10.0-327.10.1.el7.x86_64 # rpm -q systemd systemd-219-19.el7_2.9.x86_64 # rpm -q polkit polkit-0.112-6.el7_2.x86_64 Any help or guidance that can be given is appreciated.
