[support] update.php never finishes

I have two sites that I upgraded from Drupal 7.4 to 7.7. One worked fine. But on the second one when I run update.php, it says 1 pending update menu module 7001 - Rename "Primary Links" and "Secondary Links" to their Drupal 7 equivalents. But when I run this update, it never finishes. It is stuck in the Run updates step. What do I do? -- James A. Rome URL: http://jamesrome.net
