I got a pretty positive response: Thank you for the very detailed and full report! We've experienced the same (or very similar problem), when memory cgroups were staying in the dying state for a long time, so that the number of dying cgroups grew steadily with time. I've investigated the issue and found several problems in the memory reclaim and accounting code. The following commits from the next tree are solving the problem in our case: 010cb21d4ede math64: prevent double calculation of DIV64_U64_ROUND_UP() arguments f77d7a05670d mm: don't miss the last page because of round-off error d18bf0af683e mm: drain memcg stocks on css offlining 71cd51b2e1ca mm: rework memcg kernel stack accounting f3a2fccbce15 mm: slowly shrink slabs with a relatively small number of objects -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1792349 Title: Memory leaking when running kubernetes cronjobs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1792349/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
