Bug description:
Playing an mp4 on a Samsung Galaxy Nexus using today's image (3 Oct
2013) for 30 minutes I observed that init is busy and also consuming
heap quite rapidly.
Attached is the output from running health-check (found in PPA:colin-
king/white) on init pid 1114.
Key points:
1. messages being read/written at ~600 messages a second, hence the high
context switch rate and ~4.9% CPU load.
2. heap consumption: ~30K a second using brk() and 2K a second via mmap
To reproduce:
Install health-check:
sudo add-apt-repository ppa:colin-king/white
sudo apt-get update && sudo apt-get install health-check
Download a large mp4 to the phone. Keep screen from blanking using:
sudo powerd-cli display on bright &
then play the mp4:
dbus-launch mediaplayer-app test.mp4
--desktop_file_hint=/usr/share/applications/mediaplayer-app.desktop
--stage_hint=main_stage
And then observe that init is busy for 300 seconds:
ps -e | grep init
1 ? 00:02:56 init
348 ? 00:00:00 init
1114 ? 00:03:22 init
sudo health-check -p 1114 -d 300
Attached are my results for a 30 minute run.
