title: Internal Server Error 500 in only one Storeview of Magento
body: <p>I'm running Magento 1.7.0.0 multistore and a few times a day I get the famous "Internal Server Error 500" in my browser. </p>
  
  <ul>
  <li>When navigating to Magento backend or a different Magento Storeview, the backend and the Storeview are still available and show no Internal Server Error. </li>
  <li>Visiting the homepage or any category page, product page or cms page doesn't make a difference. </li>
  <li>After flushing /var/sessions, the frontend is available again. </li>
  </ul>
  
  <p>So, what I've done already: </p>
  
  <ul>
  <li>I think it's not related to permissions, as these are set properly. I ran Magento-Cleanup.php a few times, and that's not changing or helping.</li>
  <li>I checked settings in htaccess. These seem to be good.</li>
  <li>SID is off. With or without SID doesn't make a difference</li>
  <li>Logs show no issues that could cause this. </li>
  </ul>
  
  <p>Help! </p>
