Upon wake, when systemd sees the clock has advanced beyond the 3 minute watchdog timeout, it will kill and restart services that have the watchdog enabled. Is there any logging I'm hoping we'll be able to participate more freely in upstream systemd development here, but until then it might be limited to obtuse reports of trivial issues like this one. 9.
