This appears to be caused by apt_check / apt_check.run(). Exchanging result = apt_check.run() with result = (0, 0) in /usr/bin/update-notifier-kde prevents this growth of memory usage (there's minor growing still though - according to ps).
apt_check is in /usr/lib/update-notifier/apt_check.py (from update- notifier-common). I've quickly looked into it: it used apt_pkg, which may be causing it. btw: a comment in update-notifier-kde says that the whole checkNewPackages may not be required in the future: checkNewPackages = True #kpackagekit has a new package notifier but it's broken so use this Looks like some memory profiling is required here. ** Changed in: update-notifier-kde (Ubuntu) Importance: Undecided => Medium ** Changed in: update-notifier-kde (Ubuntu) Status: Confirmed => Triaged -- Memory leak in update-notifier-kde https://bugs.launchpad.net/bugs/289264 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
