The main loop in the master is as follows:
set an alarm for 1000s
do an EPOLL_WAIT for up to 500s and handle any child process
events, or short-term timer requests that are implemented
around the EPOLL_WAIT timer.
respond to sighup (the sighup flag is set by a signal handler)
respond to sigchld (the sigchld flag is set by a signal handler)
It would be worthwhile to see what strace reports when you leave
it running. If strace reports nothing in 500s then EPOLL_WAIT is
not working. If strace reports nothing after 1000s then the alarm
timer is also not working.
