Subject Re: IT WON'T BREAK!!! (was Re: New Excalibur--Time to redo your Cocoon Load Tests)

That sounds like a problem I'm just having too, I've got quite a bit of 
XSP in my test cases, and Tomcat is just dieing without any errors 
displayed at all. In fact I've looked in every log I can think of (tomcat,
  cocoon, system) and I can't see any evidence of anything going wrong!

Stuart.
