I ran health-check (ppa:colin-king/white) against unity-panel-service while navigating menus on gimp and thunderbird for 60 seconds and I observed on average over 60 seconds:
about 53 minor page faults per second, nearly 1900 context switches a second, over 260 recvfrom() syscalls per second, over 8500 poll() syscalls that timed out with a zero timeout (which means there poll is being abused somewhere), nearly 175K of heap growth per second via brk() nearly 550K of memory growth per second via mmap() Attached is the full log. This is a seriously leaky process with some excessive power consuming polling going on. ** Attachment added: "health-check analysis" https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1199877/+attachment/3893898/+files/health-check.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1199877 Title: unity-panel-service memory leak and 100% CPU usage To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-consumption/+bug/1199877/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
