 * I have several blogs on the same VPS server (all WP 3.0.4 and Supercache 0.9.9.8)
 * As of a couple of days ago, I noticed the following error in the error_log (of
   all blogs):
 * PHP Notice: Undefined variable: php_fd in /wp-content/plugins/wp-super-cache/
   wp-cache-phase2.php on line 572
 * Anything serious? Can I do anything to avoid it?
 * thanks,
 * Peter
