title: Cannot connect to Apache HTTP Server from outside after awhile
body: <p>we have a problem with our Website not beeing accessible from outside (not localhost) after some time (2-3 days).</p>
  
  <p>We use an Apache HTTP Server 2.4. There are 4 Websites hosted on the Server, mainly using port 443 using a self signed server certificate. So far, everything is running fine. Since I added a new Website using Alias directive and PHP, after a while <strong>all</strong> Websites are not accessible from remote anymore. However, I can access them from localhost on the server.</p>
  
  <p>The error log does not show any entries at the time the websites are not accessible anymore. We currently fix the problem by simply restarting the Apache HTTP Server and everything is back to normal. The problem is, that we need the service to be available 24/7.</p>
  
  <p>This is the current httpd.conf:</p>
  
  <pre><code>Listen 443
  SSLSessionCache "shmcb:${SRVROOT}/logs/ssl_scache(512000)"
  SSLSessionCacheTimeout 300
  &lt;VirtualHost *:443&gt;
      DocumentRoot "D:/htdocs"
      ServerName myserver.net:443
  
      Alias /site2 "${WEBROOT}/site2"
      Alias /site3 "${WEBROOT}/site3"
  
      ScriptInterpreterSource Registry-Strict
      Options +ExecCGI +FollowSymLinks -Indexes
      DirectoryIndex index.cgi index.html index.php
  
      SSLEngine on
      SSLCertificateFile "${SRVROOT}/ssl/server.crt"
      SSLCertificateKeyFile "${SRVROOT}/ssl/server.key"
  &lt;/VirtualHost&gt;
  </code></pre>
  
  <p>and</p>
  
  <pre><code>LoadModule php5_module "${PHPROOT}/php5apache2_4.dll"
  &lt;IfModule php5_module&gt;
      AddHandler application/x-httpd-php .php
      PHPIniDir "${PHPROOT}"
  &lt;/IfModule&gt;
  </code></pre>
  
  <p>Does anyone have an idea where to look at? Would very much appreciate.</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>The server was running for 13 days, and then we had to restart it due to some configuration changes. It took 1 day and the problem came back. I looked at the server-status page, but i cannot find a clue what might be the problem:</p>
