Multiple user issue in Web Dynpro - urgent

I have created an application using Web Dynpro for Java that is being called from MAM 3.0. We are currently in testing and we have about 30 people that are calling the application at the same time. When doing that, some people get in and get results and others don't. I

s there a limitation as to how many people can call the application at the same time? Also, is there a time out flag that woud cause the browser to disconnect from the application after a certain amount of time?

The application calls a function module in R3, could there be a problem with the number of people calling this function module?

I am new to Web Dynpro and don't understand all of the things it can do and can't do.

This could postpone our go live so any help will be greatly appreciated.

    30 concurrent users is no problem from a framework perspective.

    Maybe there is a problem with the backend (JCO connections not released?). I think you should investigate in this direction.

    Error might be due to JCO connection pool is exhausted.

    U can increase maximum pool size of JCO connection pool or

    U can change scope of model objects from APPLICATION_SCOPE to TASK_SCOPE .

    For more info go through this weblog.
