Created attachment 481417 [details] more verbose strace log Description of problem: The system dbus daemon consumes 100% CPU after a user logs in. strace shows fast | poll([{fd=3, events=POLLIN}, ... {fd=41, events=POLLIN}, ...|], 36, 24525) = 2 ([{fd=41, revents=POLLNVAL}, {fd=43, revents=POLLNVAL}]) | poll([{fd=3, events=POLLIN}, ... {fd=41, events=POLLIN}, ...|], 36, 24525) = 2 ([{fd=41, revents=POLLNVAL}, {fd=43, revents=POLLNVAL}]) sequences. Before the first of these polls, strace shows that dbus client closed connection (POLLHUP) and the dbus daemon closed the sockets. Version-Release number of selected component (if applicable): dbus-1.2.24-3.el6.x86_64
