Kevin Chen commented on WFLY-6561:
----------------------------------
The "QuartzWatcherService" is configured to be run every minute. Below is the code for the TimerConfig and verified by watching logs:
{code:java}
ScheduleExpression expression = new ScheduleExpression();
expression.second("0").minute("*").hour("*").start(new Date(System.currentTimeMillis() + 6000));
// Triggers @Timeout method above.
final TimerConfig config = new TimerConfig();
config.setPersistent(false);
timerService.createCalendarTimer(expression, config);
{code}

> On Wildfly10, we are experiencing intermittent problems where on server startup, an @Timeout annotated method can be executed hundreds of times in a second (log below). Going through the references to the @Timeout methods and the @Scheduled methods, all scheduled methods are set to be non-persistent (ex: timerConfig.setPersistent(false), persistent=false) so we don't know how this could occur. It is not consistent and our only solution has been to kill the Wildfly10 server process and restart.
