 For one of my blogs, an upgrade from 3.0.5 to 3.1 failed.

 I debugged the issue to '''wp_cache_flush()''' hanging during the upgrade
 process.

 To get the DB upgrade to go thru, this is the hack that I did:

 File: /wp-admin/includes/upgrade.php

 Method: wp_upgrade()

 Comment out the call to '''wp_cache_flush()''' in line '''364'''.

 The DB upgrade went thru properly and I was able to login again.

 I have been using ''W3 Total Cache'' on my blog. I'm not sure if that is
 what was conflicting during the upgrade.
