Subject EJB timers stop working.
Date Wed, 11 Feb 2015 14:48:13 GMT
Hi all.

In production under load, we experienced a case were a particular timer
stopped working.

I thought maybe a runstime exception stops a ScheduleExpression, but could
not simulate this. Glassfish I know was very sensible to this.

Could a low EJB timer thread seeting cause a timer to stop, working.

We use tomee 1.7

The timer is initialized like that.

@Singleton
@Lock(LockType.READ)
@Startup
public class CommEtaUpdateCacheTimer {

    @Inject
    private TimerScheduler scheduler;

    @PostConstruct
    public void doit() {
        final ScheduleExpression schedule = new ScheduleExpression()
                .hour("*")
                .minute("*")
                .second("*/5");

        scheduler.scheduleEvent(schedule, new
CommEtaUpdateCacheTimerEvent());
    }

    public void observe(@Observes CommEtaUpdateCacheTimerEvent event) {
/*
processing code.
*/

    }

    public static class CommEtaUpdateCacheTimerEvent {
    }
}
