今天我意识到我的服务器上没有运行一些 cron 任务！在日志文件中我发现了以下内容：
Mar 13 03:30:01 osp-server anacron[7261]: Anacron 2.3 started on 2012-03-13

Mar 26 20:21:30 osp-server anacron[7261]: Job `cron.daily' terminated (mailing output)
我理解的对吗？/etc/cron/cron.daily 中的一项任务直到 3 月 26 日 20:21:30 才完成，因此没有运行其他 cronjobs？
如果是，我该如何结束这种行为？例如，如果任务在 2 小时内未完成，是否会自动终止？
