In www mode i have generated a script and ran for 1 user.It ran fine inserting a record in the table as expected.With 2 users also it is running fine inserting 2 records in the table.But when i ran more than 2 users the no. of records inserted is always more than expected.For example for 5 user it is around 17,for 6 users it is around 27 etc.,
I have set the parameter for the method DO_SetMaximumRetries as 0.

I hope some requests are fired multiple number of times(based on timeout of the the request) irrelevant of the parameter set in the method DO_SetMaximumRetries().
Can any one tell what goes wrong.
Thank you for the solution.
