We have a pretty standard installation of CentOS 6.4 on our workstations. We've been running into issues where kdm crashes every once in a while when someone tries to log in on the console. The only way to recover when it happens seems to be to restart kdm (kill -HUP `pgrep -f /usr/bin/kdm`) (or reboot of course) and it never seems to happen twice in a row. I am not sure where to start looking to see why kdm would crash like this so intermittently. Does anyone have any idea why this might be happening? -- Thanks! Miranda
