系统重启后，在重启前（存在内存不足的问题）返回以下错误。
The Phusion Passenger application server tried to start the web application by communicating with a helper process that we call a "preloader". However, this helper process sent a response that looks like gibberish.
The response is as follows:
响应是一个空白。 虽然建议填写bug报告，但我不怀疑这是一个bug，因为之前一切都在工作。"唯一提供的诊断程序表明。
PID 1554
x Receive and process preloader response — 0.4s
这该怎么办？
服务器重启可以解决这个问题。 结果满意，动机不满意...
