 * Hello!
 * My site started, from nowhere, to get some 500 Internal Server Error messages.
 * I noticed that that was a problem with WP-Cache. When the plugin expires ALL 
   the cached pages, I get this error. Then, I just have do delete the file wp_cache_mutex.
   lock from the /cache dir and the site get up and run.
 * What is this? How can I fix it?!
