Php symfony2命令被杀死未知原因

我得到了一个短信cronjob运行与我的服务器每秒钟与flock

而我的剧本被杀的异常，为什么我说它是异常的

有时，我的脚本运行并发送大约2000条短信，没有任何问题

有时现在，我的脚本运行一个新的批173短信和总是有被杀随机

调度员来了

我将消息保存在日志中，以便我可以查看

在我的调度程序中，每个继任者都会失败

印刷品

我查了一下我的日志文件，有……被杀了

有时……被杀

我如何检查为什么会发生死亡？任何我应该如何修复或调试它，错误消息是如此简单，刚刚被杀死，没有其他消息让我检查它…如果你想阅读更多的源代码，请告诉我，非常感谢谁在这方面的帮助，首先感谢

**update 1:**

我在谷歌上搜索了一段时间后，很多人说这是因为内存泄漏导致的错误，所以我添加了这个

print(sprintf('Memory usage (currently) %dKB/ (max) %dKB', round(memory_get_usage(true) / 1024), memory_get_peak_usage(true) / 1024));print("\r\n");

在dispatcher foreach$recipients中，作为$contactPhone{

下面是结果

当服务器没有配置交换并且进程内存不足时，我看到很多这样的事件被杀死。如果你运行循环一段时间，你可能会在某个地方出现内存泄漏。另外，请检查fingers\u Cross logging handler，因为它会缓冲所有东西，以防你需要它。fingers\u Cross log？你是指symfony错误日志吗？我已经在一个地方检查过了pp/logs/prod.log和dev.log，我没有发现任何特殊之处。cron每秒钟运行一次，检查是否有可用的sms发送，foreach循环它如果有，如果内存泄漏，2000++sms如何发送而没有问题？您可能希望实现队列消息传递。顺便说一句，您可以启用php cli e错误日志，并确保日志文件可由php cli写入。

print(sprintf('Memory usage (currently) %dKB/ (max) %dKB', round(memory_get_usage(true) / 1024), memory_get_peak_usage(true) / 1024));print("\r\n");
