[BUG] - WithLimitConcurrentJobs causes jobs not to resume

[jmutschler]

Describe the bug

WithLimitConcurrentJobs causes scheduled jobs not to run after StopJobs() then Start()

To Reproduce

func main() {
    s, err := gocron.NewScheduler(
        gocron.WithLimitConcurrentJobs(2, gocron.LimitModeReschedule), // this causes the bug
    )
    if err != nil {
        panic(err)
    }

    // add a job to the scheduler
    _, err = s.NewJob(
        gocron.DurationJob(
            10*time.Second,
        ),
        gocron.NewTask(
            func(a string, b int) {
                fmt.Println(time.Now().Format("2006-01-02 15:04:05"), a)
            },
            "hello",
            1,
        ),
    )
    if err != nil {
        panic(err)
    }

    s.Start()

    // run schedule for 20 seconds
    select {
    case <-time.After(20 * time.Second):
    }

    // restart the scheduler
    s.StopJobs()
    s.Start()
    fmt.Println("Restarted Scheduler")

    // run schedule for another 30 seconds
    select {
    case <-time.After(30 * time.Second):
    }

    err = s.Shutdown()
    if err != nil {
        panic(err)
    }
}

Output:

2024-04-29 09:08:59 hello
Restarted Scheduler

Expected output:

2024-04-29 09:10:21 hello
Restarted Scheduler
2024-04-29 09:10:31 hello
2024-04-29 09:10:41 hello
2024-04-29 09:10:51 hello

Version

v2.5.0

Expected behavior

Scheduled jobs should resume after Scheduler.Start()

@jmutschler yes this is definitely a bug. Sorry, I haven't had a chance to dig into the code yet and see what's getting hung up.

[jmutschler]

No problem. I appreciate your time on this!

[JohnRoesler]

Found the issue, easy one to fix. Should be out here pretty soon

Thank you @JohnRoesler!
