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 Touch seeded packages, which is subscribed to dialer-app in Ubuntu. https://bugs.launchpad.net/bugs/1388594 Title: [TOPBLOCKER] dialer app can thrash cpu after caller hangs up on you Status in “dialer-app” package in Ubuntu: Incomplete Bug description: summary dialer app can thrash cpu after caller hangs up on you steps: 1. answer call from someone using snap decision bubble 2. talk for a while 3. let the caller hang up on you expected results: dialer app isn't using 100% cpu after call actual results dialer app continues to thrash cpu snap shot from top 5 minutes after call PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 7412 phablet 20 0 253352 50876 25296 S 100.0 5.2 11:41.13 dialer-app 751 message+ 20 0 9480 6680 756 S 1.3 0.7 4:03.64 dbus-daemon version info: [service] base: system-image.ubuntu.com http_port: 80 https_port: 443 channel: ubuntu-touch/ubuntu-rtm/14.09-proposed device: krillin build_number: 140 version_detail: ubuntu=20141031.1,device=20141028-3ca60be,custom=1414598646,version=140 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dialer-app/+bug/1388594/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
