          Using the latest version currently, I encountered a situation where the execution occurs twice. After multiple tests, I found that the occurrence of execution twice is sporadic, and I am not sure under what circumstances it occurs.

Starting server at 0.0.0.0:8881...
{"@timestamp":"2023-10-27T16:43:41.435+08:00","caller":"handler/routes.go:25","content":"--running--","level":"info"}

{"@timestamp":"2023-10-27T16:48:00.000+08:00","caller":"handler/routes.go:25","content":"--running--","level":"info"}

my code:

      s.
	Cron("*/3 * * * *").
	SingletonMode().
	WaitForSchedule().
	Do(func() {
		logx.Info("--running--")
	})

However, when I switched to a lower version for testing, I found that the execution twice situation did not occur.

require(
        //github.com/go-co-op/gocron v1.35.2 // indirect
        github.com/go-co-op/gocron v1.16.3
)

@leafney if you're up for it. Check out the v2 branch. It's in early testing, but this should be completely solved there!

Sure. I'll try it.

[leafney]

func V2Test() {
	s, _ := gocron.NewScheduler()

	s.NewJob(
		//gocron.DurationJob(time.Second*5),
		gocron.CronJob("*/2 * * * *", false),
		gocron.NewTask(func() {
			log.Println("--v2 v2 v2--")
		}),
		gocron.WithSingletonMode(gocron.LimitModeReschedule),
	)

	s.Start()
}

The v2 version did not find repeated executions, perfect.
