What is the max length of nodejs execFile callback params "stdout"?
<p>I use child_process to excute yslow.js by phantomjs. 
Example(CLI): </p>

<pre><code> phantomjs yslow.js --info all --format json url
</code></pre>

<p>We can get the analytic data that yslow.js return to me after analyzing.</p>

<p>But sometimes the data yslow.js return to me can not be a complete json file. Is seem the callback params "stdout" can not be too a large length data. I guess If the data is too large can infect the params stdout...</p>

<p>Has anyone ever encountered such a problem ?</p>
