title: PHP Connection Reset on Large File Upload Regardless Correct Setting
body: <p>I am having a very common problem which it seems that all the available solutions found are not working.</p>
  
  <p>We have a LAMP server which is receiving high amount of traffic. Using this server, we perform a regular file submission upload. On small file uploads, it works perfectly. On files of around 4-5MB, this submission upload failed intermittently (sometimes it works but many times it failed). </p>
  
  <p>We have the following configuration on our PHP:</p>
  
  <pre><code>max_input_time: 600
  max_execution_time: 600
  max_upload_size: 10M
  post_max_size: 10M
  </code></pre>
  
  <p>Apache setting:</p>
  
  <pre><code>Timeout: 600
  Keep-Alive Timeout: 15
  Keep-Alive: On
  Per Child: 1000
  Max Conn: 100
  </code></pre>
  
  <p>Thus, I wonder if anyone can help me with this. We have found the issues and solutions online but none of them work in our case.</p>
  
  <p>Thank you so much. Any input / feedback is much appreciated!</p>
