Package: systemd Version: 252.38-1~deb12u1 Severity: normal X-Debbugs-Cc: [email protected]
Dear Maintainer, I have a server configured to automatically suspend using "systemctl suspend" after X minutes of inactivity on specific monitored ports. When traffic is detected on those ports, the gateway wakes the server via Wake-on-LAN. I have a systemd timer set to reboot the server sometime between 4 and 5 a.m. The timer looks like this: [Unit] Description=Daily reboot [Timer] OnCalendar=*-*-* 04:00:00 RandomizedDelaySec=3600 WakeSystem=true Unit=reboot.target [Install] WantedBy=timers.target Each time the server wakes from suspend, the elapsed time is recalculated and shifts progressively further into the future, significantly surpassing the 4 to 5 o'clock window. I attempted to fix this by enabling "FixedRandomDelay=true", but it didn't affect the behavior. These logs show the most extreme instance I've seen to date, every time "Time change, recalculating next elapse." is logged, systemd wakes from suspend and the elapse time has slipped all the way to 10 a.m., which is 5 hours behind schedule. journalctl logs (LogLevel=debug + FixedRandomDelay=true): -- Boot -- Jul 28 06:45:47 srv001 systemd[1]: daily-reboot.timer: starting held back, waiting for: time-set.target Jul 28 06:45:47 srv001 systemd[1]: daily-reboot.timer: Adding 48min 58.106261s random time.
