Subject Re: More than 20 users not able to access the application...
Date Mon, 08 Feb 2010 15:05:44 GMT

Our application is Online Vehicle Booking for Rental.

I'm doing Load Testing using HP Load Runner and I've recorded a script that
contains booking a vehicle (submitting data to MSSQL Server 2008) then did a
load testing with 20 concurrent users.Meanwhile I'm trying to do booking
manually from the browser.

But booking window is loading for long time and only one message i'm getting
is 200 Aborted.(In Firebug from Mozilla Firefox).but Internet explorer not
showing anything.

In log I'm getting this message..
org.hibernate.LazyInitializationException: could not initialize proxy - the
owning Session was closed
