node.js - Node.js | JavaScript堆内存不足，但HEAP只有1GB

问题描述

我收到此错误：

FATAL ERROR: invalid table size Allocation failed - JavaScript heap out of memory

但我正在使用--max-old-space-size=12288，我有 16GB 的内存

使用process.memoryUsage()我可以看到堆只增加到~1GB；此外，错误总是发生在同一行代码中，即types.js:~94，这是我正在使用的库的一部分。

这让我觉得某处存在错误，也许在我传递给函数的参数中，但我不知道如何发现它。

我应该寻找什么？

完整的错误是：

types.js的第94行是decode函数的入口点，定义如下：

  var buffer12 = struct.Buffer(12)

  function decode (buffer, offset, end) {
    var bvalue = buffer12.decode(buffer, offset, end)
    for (var stop = 0; bvalue[stop] !== 0; ++stop);
    for (var i = stop; i < bvalue.length; ++i) {
      if (bvalue[i] !== 0) throw new Error('Found a non-null byte after the first null byte in a null-padded string')
    }
    return bvalue.slice(0, stop).toString('ascii')
  }

解决方案

你有一个错字！

正确的用法是node --max-old-space-size=4096 somescript.js

在这种情况下，4096 是 4gb，请根据您的情况进行相应调整...

运行node --v8-options所有有效 v8 选项的列表，或检查此 v8 标志列表
