This problem can now be demonstrated with a single connection to upstart that makes the following calls:
dbus_connection_open() nih_dbus_proxy_new () The problem is not seen if the app instead calls: - nih_dbus_connect (upstart_session, disconnect_handler) - nih_dbus_proxy_new () - nih_main_loop() Or, - nih_dbus_connect (upstart_session, NULL) - nih_dbus_proxy_new () - nih_main_loop() Specifically, the problem appears to be that when an app calls dbus_connection_open(), one or more of the functions in nih_dbus_setup() should be being called to allow libdbus to interrupt the apps main loop and request callbacks are run to clean up resources. -- 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: uevent spam causes session upstart to consume massive amounts of memory on Ubuntu Touch Status in Upstart: New Status in “linux” package in Ubuntu: Invalid Status in “systemd” package in Ubuntu: New Status in “unity” package in Ubuntu: New Status in “upstart” package in Ubuntu: Fix Released Status in “linux” source package in Saucy: Invalid Status in “systemd” source package in Saucy: New Status in “unity” source package in Saucy: New Status in “upstart” source package in Saucy: Fix Released 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.
