我在laravel中构建了一个应用程序，假设所有国家/地区每4小时使用webhose.io获取新闻。它似乎在某个时候工作正常。但是一段时间后再次停止并重新启动。我不知道如何追踪出了什么问题。

CRON工作细节
# Edit this file to introduce tasks to be run by cron.
#
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
# and what command to run for the task
#
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use '*' in these fields (for 'any').#
# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.
#
# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
#
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
#
# For more information see the manual pages of crontab(5) and cron(8)
#
# m h dom mon dow command
* * * * * php /var/www/html/connect/artisan schedule:run >> /root/logs/sec.log 2>&1
00 22 * * * /opt/dbbackup/db.sh /dev/null 2>&1

编辑：
随着时间的推移添加了withoutoverlapping()日志我发现新闻更新任务每4小时运行一次，但是被其他任务引起了反响。
if (App::environment('live')) {
$schedule->command('GetNewsUpdates:getnews')->cron('0 */4 * * *')->withoutOverlapping(10)->sendOutputTo('/root/logs/laravel_output.log');

简单来说当CRON守护进程调用php artisan schedule：每分钟运行命令时，将启动Console Kernel并在App\Console\Kernel::schedule()方法中定义的作业将注册到调度程序中。
schedule()方法将Illuminate\Console\Scheduling\Schedule的一个实例作为唯一的参数，这是用于记录您提供的作业的计划管理器，并决定每次CRON守护程序ping它时应该运行什么。
现在转向你的问题。
as @ hoseinz3提到几乎是对的
Laravel如何阻止您的预定作业重叠？
有时，计划的作业比我们最初的预期花费更多的时间来运行，这导致另一个作业实例在第一个作业尚未完成时启动，例如假设我们运行的作业每分钟生成一个报告，之后有时，当数据变得庞大时，报告生成可能需要1分钟以上，因此该工作的另一个实例会在第一个实例仍在进行时启动。
在大多数情况下，这很好，但有时应该防止这种情况，以保证正确的数据或防止高服务器资源消耗。
Laravel将检查Console \ Scheduling \ Event :: withoutOverlapping类属性，如果它设置为true，它将尝试为作业创建一个互斥锁，并且只有在可以创建互斥锁时才运行该作业。
有关Mutex的更多信息
因此，当作业第一次启动时，Laravel会创建一个互斥锁，然后每次运行该作业时，都会检查互斥锁是否存在，只检查该作业是否存在。
因此，Laravel创建了一个过滤器回调方法，指示计划管理器在互斥锁仍然存在时忽略该任务，它还会创建一个在完成任务实例后清除互斥锁的后回调。
试试这个片段

use App;
use Illuminate\Console\Scheduling\Schedule;
use Illuminate\Foundation\Console\Kernel as ConsoleKernel;
class Kernel extends ConsoleKernel {
/**

protected $commands = [

protected function schedule(Schedule $schedule) {

$schedule->command('AddBirthdayNotifications:addbdaynotifications')

尝试某种CRON作业监控系统。你可以尝试目击者，这是监测Laravel Application非常好的工具。
您已经使用withoutOverlapping方法，基于Laravel documentation，这意味着当一个作业需要很长时间才能默认运行Laravel Hold新作业24小时，然后，如果没有作业运行，它会尝试运行该作业，并且您也可以更改这个数字通过withoutOverlapping论证。例如
$schedule->command('command')->hourly()->withoutOverlapping(5);
这意味着如果有运行命令，Laravel将持续5小时的新命令，之后它将再次尝试运行此命令。
Laravel同步运行cron作业，因此某些任务可以阻止其他任务。
$schedule->command('analytics:report')
->daily()
->runInBackground();
由于cron每分钟启动一次，所有计划任务都将正常启动，它们之间的延迟几分钟而不会相互阻塞。
$schedule->command('analytics:report')->hourlyAt(1); // run every hour at 1 minute
$schedule->command('analytics:report2')->hourlyAt(2); // run every hour at 2 minute
$schedule->command('analytics:report3')->hourlyAt(3); // run every hour at 3 minute
要么
$schedule->command('analytics:report')->dailyAt('13:01');
$schedule->command('analytics:report2')->dailyAt('13:02');
$schedule->command('analytics:report3')->dailyAt('13:03');
