Subject Re: Max call of service
Date Tue, 19 Aug 2008 08:40:58 GMT
Hi Michail,

The stack the you mentioned is little bit confusing. Is it the stack in a
normal process run-time or a stack that you have created? If it is the stack
in a normal program run-time where are you creating your object in the code?
Are you creating the object as a global variable?

Thanks,
Supun..
