@jamesodhunt: Please let me know what information I should provide (the output of specific commands and content of specific logs).
I don't think the init is supposed to use 50 MB of RAM or more forever after running 5000 containers or less - even after CPU goes down to 1-2% for the init process. The fact that CPU usage has gone down is an indicator that events have probably been processed and everything should be OK now, but memory usage is still high. Memory usage grows by a few bytes even when running a few containers. I can see memory usage grow by a few bytes after running every Docker container. That means it's probably using that much memory -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to upstart in Ubuntu. https://bugs.launchpad.net/bugs/1198180 Title: possible leak in upstart 1.5 Status in “upstart” package in Ubuntu: Confirmed Bug description: Description: Ubuntu 12.04.2 LTS Release: 12.04 Package: 1.5-0ubuntu7.2 Kernel: Linux XXX 3.8.0-23-generic #34~precise1-Ubuntu SMP Wed May 29 21:12:31 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux We're starting lxc containers on demand, so there's lots and lots of network interfaces going up and down. Udev emits signal, that goes to upstart-udev-bridge, and next to the upstart itself. After about 40K containers created/destroyed, upstart takes about 250MB or RAM, and it grows with every event received/send. Not only RAM is beeing used, but also init spends more time for every new event on the socket. What happens: init uses more RAM and more CPU during lifetime, when lots of network interfaces are beeing created/destroyed What is expected: init work should not change depending on number of events served technical detail: # pmap -x 1 00007f446f865000 0 237036 237036 rw--- [ anon ] 00007fffc694d000 0 24 24 rw--- [ stack ] 00007fffc69fe000 0 4 0 r-x-- [ anon ] ffffffffff600000 0 0 0 r-x-- [ anon ] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/1198180/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
