After enable watchdog in daemon zeneventd, cannot see "Performing periodic maintenance" history in log, only message "zen.zenutils.functioncache: initializing FunctionCache", but can see rawevents are being handled, so think the daemon is still running.but alway have warning " localhost zeneventd heartbeat failure". After diable watchdog and kill process, restart zeneventd daemon, it resumes. What is the daemon doing when we see event "Performing periodic maintenance" Any impact to the daemon if watchdog is enabled
When I enabled debuging by -v10, only can see zeneventd is handling event mapping.
Log sample with watchdog enabled and heartbeat failure warning:
