I ran into this problem while working with a BuddyPress installation on Rackspace Cloud Sites. To solve it I needed to change some server limitations by editing my .htaccess file. The settings I used were:

php_value memory_limit 128M
php_value post_max_size 128M
php_value upload_max_filesize 128M
php_value max_execution_time 6000000

I’m not sure if your problem requires a similar solution, but I hope this helps.
