Fatal error in Buddypress bar after batch create

Just used the batch create and successfully created 671 blogs, great!

When I hit blog number 221, I ran into a hosting error where I ran out of memory. I contacted my host, got it sorted out and continued with the remainder of the blogs.

All the blogs appear to be fine, but the following error appears in the buddybar, not on the main site, but the user blogs that were there before the batch create as well as the new ones...

Fatal error: Out of memory (allocated 41943040) (tried to allocate 35 bytes) in /home/thatmlmb/public_html/wp-includes/plugin.php on line 302

Where should I start?

Thanks,

George
