title: Webpack bundle build crashing my website everytime a user uploads an image
body: <p>I have a website where people can upload images, <strong>it used to be working just fine for like 2 weeks</strong> but now, everytime an image is uploaded, the whole website is crashing. The log just shows this after some images are uploaded:</p>
  
  <pre><code>webpack building...
  ℹ ｢wdm｣: wait until bundle finished: /index.html
  ℹ ｢wdm｣: wait until bundle finished: /robots.txt
  ℹ ｢wdm｣: wait until bundle finished: /index.html
  webpack built d08e4556b6dc12db2a92 in 2727313ms
  </code></pre>
  
  <p>From what I have experimented, it looks like the issue is with </p>
  
  <pre><code>new CopyWebpackPlugin([{
        from: helpers.root('client/public')
      }])
  </code></pre>
  
  <p>If I remove this from the webpack config, the website is working and people can upload images, but well, no one can see these images, as they won't get in the <code>dist</code> folder... I'm not sure if that's how you upload images correctly with express/webpack: I put them somewhere in the public folder of my app with <code>multer</code> and then webpack picks them up with this plugin.</p>
  
  <p>I have not changed anything in the code of the upload. It stopped working for some reason. Maybe a reboot caused this issue? I'm using an EC2 instance. I really can't figure out what's the matter. </p>
  
  <p>Has anyone ever experienced something similar?</p>
  
  <p>Thanks</p>
