  <pre><code>WARNING: [pool www] server reached pm.max_children setting (5), consider raising it
  </code></pre>
  <p>When trying to access my XenForo installation at forums.domain.com in my PHP error log.</p>
  <p>It happens every time, and I think it's causes PHP to crash, which prevents the other site on the same box from working as well.</p>
  <p>I'm using nginx with two server blocks for these two sites. One's under new. and one's under forums..</p>
  <p>Thanks.</p>
