Hi Lazy,

I had set maxprocessors to as much as 5000. And configured the timeout to
ensure nothing 
would timeout... Trust me, I got the configuration right, I have previously
spent hours 
and hours looking through the source code and practically know peruser
inside out. I even 
added my own debug, to try and figure out where it was dying, but to no use
:/

I'm guessing because You didn't provide any meaningfull information.

It's not a bug it's a feature, peruser is targeted for shared hosting
providing good separation of users performance and security wise. In
configuration each processor has MaxProcessors directive whitch sets
max number of simultanous connections being served. If your tests
require more then MaxProcessors concurrent connections you will get
503 errors.

You can raise MaxProcessors or go with some other config if You don't
need the separation that peruser provides.
