[Kernel-packages] [Bug 1235649] Re: session upstart leaks massive amounts of memory on Ubuntu Touch
jibel - thanks. It does indeed look like bug 1234743 as the trace shows a lot of the following events: :sys:cpu-device-online :sys:cpu-device-offline :sys:power_supply-device-changed This would explain the Session consuming a lot of CPU since those events are generated by the kernel, picked up by the upstart-udev-bridge which injects them into the system init event space. These events are then noticed by the upstart-event-bridge running as phablet and injected into the Session Init with the :sys: prefix. Could you run that again as strace -fFttv -s 1024 ... so we can see some timestamps? Also, please attach /var/log/udev and the output of 'ls -al /proc/$session_init_pid/fd/'.

From info provided by jibel... Forcing a log flush (#25) doesn't resolve the high memory usage (as we'd expect, but worth ruling out).

[Kernel-packages] [Bug 1235649] Re: session upstart leaks massive amounts of memory on Ubuntu Touch
To summarise: there are 2 problems here: 1) The kernel spamming userspace with udev messages on mako+maguro (grouper doesn't appear to be affected but not independently verified yet). 2) Upstart not releasing memory once the kernel has finished spamming userspace (artificially forced by running stop upstart-event-bridge as user 'phablet'). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1235649 Title: session upstart leaks massive amounts of memory on Ubuntu Touch Status in “linux” package in Ubuntu: Confirmed Status in “upstart” package in Ubuntu: Confirmed Status in “linux” source package in Saucy: Confirmed Status in “upstart” source package in Saucy: Confirmed Bug description: using ubuntu touch image 82 i see the session init consume about 10MB per minute as long as the screen is on with Mir. running the same session with surfaceflinger only consumes 1MB per minute. in both cases the system starts to swap heavily at some point, making the UI unresponsive. http://paste.ubuntu.com/6196223/ has the top output of a Mir session after 30min, the UI just got completely unresponsive when this snapshot was taken. http://paste.ubuntu.com/6196332/ is the top output of a surfaceflinger session where the screen was off for about 10min apparently the leak only occurs while the screen is on, it seems to be permanently there but in the case of surfaceflinger it hits less hard.

I can no recreate the issue with memory not being freed by running: http://paste.ubuntu.com/6205552/. This is recreatable on i386 desktop images so although problem (1) in #27 is h/w specific, problem (2) is not. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1235649 Title: session upstart leaks massive amounts of memory on Ubuntu Touch Status in “linux” package in Ubuntu: Confirmed Status in “upstart” package in Ubuntu: Confirmed Status in “linux” source package in Saucy: Confirmed Status in “upstart” source package in Saucy: Confirmed Bug description: using ubuntu touch image 82 i see the session init consume about 10MB per minute as long as the screen is on with Mir. running the same session with surfaceflinger only consumes 1MB per minute. in both cases the system starts to swap heavily at some point, making the UI unresponsive. http://paste.ubuntu.com/6196223/ has the top output of a Mir session after 30min, the UI just got completely unresponsive when this snapshot was taken. http://paste.ubuntu.com/6196332/ is the top output of a surfaceflinger session where the screen was off for about 10min apparently the leak only occurs while the screen is on, it seems to be permanently there but in the case of surfaceflinger it hits less hard.
