If I increase it from 50 to 75 or 100 then only issue Which is why you can be pretty sure the problem isnt with JMeter, your app cant handle this level of concurrency. Its possible the problem may still be in your script, but really nothing that you can do in a client , should cause the application to throw the error message. Can you monitor the VM memory being utilised on your application, the problem seems to be when you add something in session.
