[Trinidad] problem in stress test

[Rogerio Baldini das Neves <ro...@powerlogic.com.br>]

Hi Guys,

 

I have tried to do a stress test in Trinidad Demo application
(trinidad-demo-1.2.8.war) and it's returning some errors.

When it's running with 10 or 15 simultaneous request everything is fine. And
with a quick response time.

 

But some problems occur when I increase this value.

When running with over 20 simultaneous users, about 20% of request present
the error below:

 

SEVERE: Could not find saved view state for token  63974241

My stress test is very simple:

-Thread Group [Number Of Threads = 30]

                -      HTTP Cookie Manager [Clear cookies each iteration ? =
checked ]

-          HTTP Request [Path =
/trinidad-demo-1.2.8/faces/components/table.jspx, Method=GET]

                               Regular Expression Extractor[view = <input
type="hidden" name="javax\.faces\.ViewState" value="(.+?)">]

-          HTTP Request [Path =
/trinidad-demo-1.2.8/faces/components/table.jspx, Method=POST]  Clicking
first "Action" button.

                                               Parameter:
javax.faces.ViewState=${view}

-          Aggregate Report

 

Does Anybody know about this error ? 

Is it a bug or a misconfiguration ?

 

It's very serious because I have a few applications developed with Trinidad
and it's impossible to release its to startup in production.

 

Thanks a lot,
