Encountered last night (2025-03-30) on Debian 12 on systemd package 252.36-1~deb12u1. 100% CPU usage by /sbin/init stopped either by stopping .timer units manually or by waiting until clock changed 00:59:59Z -> 02:00:00+0100.
This is evidenced by one of the multiple affected machines logs showing .timer-covered .service units stopped restarting exactly at that time. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/2060082 Title: Dublin timezone cause systemd cpu high Status in systemd package in Ubuntu: Confirmed Bug description: Systemd version(249) in Jammy Jellyfish is too old, When using the Dublin time zone for daylight saving time switching，the CPU usage will suddenly increase to 100% starting from 2024-03-31 00:00:00 and last for 1 hour, but return to normal at 2024-03-31 02:00:00. plz backport the bugfix to v249 or update 255 version in Jammy Jellyfish to fix it. thank you.
