agenda npm runs only 4 times

I need a job scheduler that runs a couple of jobs in a specific time interval. So, I used agenda module for doing this task. What happens is when the server is restarted the jobs get executed and this happens for 4 times in regular interval basis and after that agenda stops working without throwing any error. I tried canceling the jobs and stopping agenda whenever the server stops. So that agendaJobs creates new collection every time the server is restarted. But still, I experience the same issue. Since, I have multiple node instances running, I need the jobs to run only once in that time interval. Hence, I used agenda. Is there any different schedulers which can do the same or am I doing something wrong?
