nodejs内存不足
我今天遇到一个奇怪的问题。对于其他人来说,这可能是一个简单的答案,但这让我感到困惑。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);
}
addresses.length
addresses // memory goes from a few megs to over a gig in seconds when trying to print this
我得到了这两个错误之一…第一个是在节点的解释器中运行此代码时,第二个是通过nodeunit运行它时:
严重错误:CALL_AND_RETRY_2分配失败-内存不足
严重错误:JS分配失败-内存不足
回答:
当我尝试访问阵列时会发生这种情况。但是获取长度却没有。

16777216
