I am getting similar symptoms (media-hub-server high cpu) , although I didn't see unity8 restarting (perhaps it did and I didn't notice?).
I have attached a tarball of strace (clipped because it was just the same after a point), gdb backtrace and a core file generated from inside gdb for media-hub-server. ** Attachment added: "media-hub-server-debug.tar.xz" https://bugs.launchpad.net/ubuntu/+source/dbus-cpp/+bug/1380848/+attachment/4252111/+files/media-hub-server-debug.tar.xz -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to dbus-cpp in Ubuntu. https://bugs.launchpad.net/bugs/1380848 Title: [TOPBLOCKER] Apps and services use large amount of CPU after unity8 resets Status in Media Hub: Triaged Status in “dbus-cpp” package in Ubuntu: New Bug description: I noticed that media-hub-service can get into a state where it uses a large amount of CPU.
