我正在尝试使用OWA的事件队列处理功能，并在终端上运行以下命令：
php /var/app/current/web/owa/cli.php cmd=processEventQueue
这样做，我得到以下结果：
21:43:13 2019-06-20 7927 [console_log] About to process event queues: incoming_tracking_events,processing
21:43:13 2019-06-20 7927 [console_log] receive event.

最后一行之后，没有错误，它只是停止了。 events.txt文件不再存在，而是已将一个文件添加到“未处理”文件夹，所有其他未处理的日志文件仍然存在。至关重要的是，什么都没有添加到数据库中。
有人可以解释这个问题吗？ 没有数据库连接错误或权限被拒绝错误，因此无法解决如何清除此积压的事件...
