Actually, someone, I think Ioi, said something about it getting overloaded if your profile gets too many views, either by you pressing F5 (if you do, not saying you do) or by too many people simply comming in, posting at it looking at stuff and so.
I guess you also open windows in a new picture, and if there are many (1500+) people on, you should restrict yourself to opening 2-3 windows.
All this will be fixed when we get the new server in a couple of weeks :)
