Yes, so far so good. I’ll keep it at 128M and see if that holds.

Thanks for the advice.

I found nothing in the error logs to suggest a memory problem, but I went and defined(‘WP_MEMORY_LIMIT’, ‘128M’); and things seem to be stable now.

I have added all the sites back and so far no white screens … which is great news.

Is it OK to leave the MEMORY_LIMIT at 128M? What is the recommended LIMIT for performance on a WPMU install with around 250 sites?

(and thanks for your help)

Sure, that explains why it breaks after I remove Buddypress, but why the blank white screen when Buddypress is still installed?

I am narrowing the problem down to having too many sites, which is weird.

For example, I deleted about 200 sites and got it working again. So when I have 30 sites assigned to admin everything seems to work fine. But after I add the 200 sites back I begin to see the WSOD as I add new sites from admin.

Anybody have any suggestions?
