nodejs内存不足 [英] nodejs out of memory

问题描述

我今天遇到了一个奇怪的问题。对于其他人来说，这可能是一个简单的答案，但它让我难过。为什么下面的代码会导致内存错误？

  var cur = 167772160; 
 var bcast = 184549375; 
 var addresses = []; 
 while（cur< = bcast）{
 cur + = 1; 
 addresses.push（cur）; 
} 
地址。长度
地址//当试图打印这个
   
 
 
我得到了这两个错误中的一个......第一个是我在node的解释器中运行这个代码而后者是我通过nodeunit运行它时：
 
 
 
致命错误：CALL_AND_RETRY_2分配失败 - 处理内存不足
 
 
 
致命错误：JS分配失败 - 处理内存不足
解决方案
当我尝试访问阵列时会发生这种情况。 
但是获得长度不是。

 16777216

 16777216

致命错误：CALL_AND_RETRY_2分配失败 - 处理内存不足
  
这是另一个SO问题，  Node.js（和chrome V8）中的内存限制与内存使用问题有关。
 
I came across a curious issue today.  This may be an easy answer for others, but it has me stumped.  Why does the code below cause a memory error?
var cur = 167772160;
var bcast = 184549375;
var addresses = [];
while (cur <= bcast){
  cur += 1;
  addresses.push(cur);
}
addresses.length 
addresses // memory goes from a few megs to over a gig in seconds when trying to print this
I get one of these two errors...the first when i run this code in node's interpreter and the latter when i run it through nodeunit:

FATAL ERROR: CALL_AND_RETRY_2 Allocation failed - process out of memory

FATAL ERROR: JS Allocation failed - process out of memory
解决方案
It happens when I try to access the array.
But getting the length does not.

... }
16777216
> addresses.length 
16777216
> addresses

Here's another SO question, memory limit in Node.js (and chrome V8) that relates to issue with memory usage.
