[scope] this is needed only in f fixed upstream by 3fb2326f3ed87aa0b26078d307ebfb299e36286d which is included in v246, so fixed in h and later the code in b is very different and doesn't appear to have the leak, per original report [original description] 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 Package: systemd: Installed: 245.4-4ubuntu3.7 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1935051/+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
