The init process is certainly leaking memory. This can be observed by starting a lot of Docker containers which exit right away. I'm able to get upstart's init process to 50-100 MB of memory usage by running 5000-20000 Docker containers which only print something and then exit.
I've looked at the code and it seems like there may be some leaks. The upstart tests are are also leaking memory. Some of that memory is leaked in the tests themselves (allocated and never freed) and some others seem to be leaking in libnih itself. Ubuntu 14.04 doesn't seem to have this problem at all. -- 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 : [email protected] Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
