[Bug 1380848] Re: Apps and services use large amount of CPU after unity8 resets


I will try to come up with a distilled down test case illustrating that
libdbus-cpp is not the cause but a symptom of the issue. Point being
that it certainly shows up in the stack traces, but it sits waiting in
all of them (specifically for the system settings crash).

  Apps and services use large amount of CPU after unity8 resets

Status in Media Hub:
Status in “dbus-cpp” package in Ubuntu:

Bug description:
  I noticed that media-hub-service can get into a state where it uses a
  large amount of CPU.

  Steps to reproduce
  1) Start music-app
  2) Play music
  3) Pause music
  4) Close the music-app
  5) $ pkill unity8 (to emulate unity crashing a resetting)

  Notice that media-hub-service is now using a large amount of CPU, note
  this [0] is the media-hub.log at the time.

  The device has to be reset to get the CPU usage back to normal.
