We have been testing for last few days and unable to reproduce. Based on the gdb trace you provided, this looks to be the same as https://code.launchpad.net/~renatofilho/address-book- service/fix-1380094/+merge/238207 where apps use 100% cpu and have dbus- cpp and other thread waits in their trace.
Please re-open if you can get this to happen again. ** Changed in: dialer-app (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1388594 Title: [TOPBLOCKER] dialer app can thrash cpu after caller hangs up on you To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dialer-app/+bug/1388594/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
