** Description changed: Hi everybody. We've meet a memory leak of pid1 process on the focal release. When we launch chef-client, several systemd .service and .timers are checked for state. Every time of this run pid1 increase VSZ/RSS on ~ 232 Kb, this don't happen on xenial and bionic releases. I straced pid1 when that leak happen and found brk call. On pmap view of pid 1 it's anon memory grow on the same address and all marked as dirty. + All that leak memory can be freed by calling systemctl daemon-reexec. Searching in systemd github repo i found this commit https://github.com/systemd/systemd/commit/3fb2326f3ed87aa0b26078d307ebfb299e36286d - it may be related to this leak. - ------------------------------------------------------------------------------------------------ + ------------------------------------------------------------------------ Environment: - Distributor ID: Ubuntu - Description: Ubuntu 20.04.2 LTS - Release: 20.04 - Codename: focal - Uname: 5.4.0-77-generic #83-Ubuntu SMP Sat May 8 02:35:39 UTC 2021 x86_64 + Distributor ID: Ubuntu + Description: Ubuntu 20.04.2 LTS + Release: 20.04 + Codename: focal + Uname: 5.4.0-77-generic #83-Ubuntu SMP Sat May 8 02:35:39 UTC 2021 x86_64 Package: - systemd: - Installed: 245.4-4ubuntu3.7 + systemd: + Installed: 245.4-4ubuntu3.7 ** Tags added: pid1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1935051 Title: systemd pid 1 memory leak To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1935051/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
