Java quartz suddenly stop firing events

I am using quartz to schedule a daily batch process, and it runs the first days, but it had happened that fires the event for 2 days or so, and then, it stops firing the job.

The java version i'm using is: java version "1.7.0_25" Quartz version (in POM): org.quartz-scheduler quartz 2.2.1

Here is my code:

Main function for the batch:

public static void main(String[] args) {

    try {

        SimpleDateFormat sd=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); 
        JobDetail job = JobBuilder.newJob(MyJobClass.class).withIdentity("MyJobClass", "group1").build(); 
        Trigger trigger = TriggerBuilder
                .newTrigger()
                .withIdentity("MyTrigger", "group1") 
                .withSchedule(
                    SimpleScheduleBuilder.simpleSchedule()
                        .withIntervalInHours(24).repeatForever())
                .startAt(sd.parse("2015-01-12 07:30:00")) 
                .build();

        Scheduler scheduler = new StdSchedulerFactory().getScheduler();
        scheduler.start();
        scheduler.scheduleJob(job, trigger);

        String strLog="Batch initiated on " + new Date();
        System.out.println(strLog);
        log.info(strLog);

    } catch (Exception e) {
        //log error
    } 


}

And here is my execute method in the job:

public void execute(JobExecutionContext arg0) throws JobExecutionException {
    generateBatchProcess();
}

public void generateBatchProcess(){

   try{
      //do lots of interesting stuff, calling MyBatis Daos, generating excel files and sending an email
   }catch (Exception e){
      //log error
   }
}

Does someone have an idea of why this happens? Is it the garbage collector something to do with this?

I'm ashamed to admit it was only a "BadProgrammerException" because I had a call to a database connection outside the try...catch block that i hadn't seen before, so the problem was that I was not reaching the database and I couldn't figure it out with the log information (the database connection was intermitent). After I found this out, I corrected the database issue and quartz worked ok.
