Just curious Tony, what site is this? webfriendsnow.com I am Rolling Laughing at this. You went and tried to fake people into thinking your site had members by running a profile generator that creates a ton of fake profiles with thumbnails and then you turned on a traffic generator to impersonate people using the site when they aren't...
Now, your site is crashed because your site is visiting your site more times in a minute than your server can handle. ROFLMAO!
This is why you don't try to lie as the webmaster about what your site has. You need to FTP into the site, if you can, and jerk that traffic generator out of there. That will cause some additional errors, but none that you can't fix by getting into your sites phpMyAdmin and dropping the table that the traffic generator has created and is linking back onto the site with.
I'm surprised your host hasn't shut this thing down for this stunt.
Curious though, how many people did you attempt to impersonate being online before you crashed it out? Please tell us, we're begging to know.
