Hi Michele,

the state does not matter. The calls to the service are independent. So the WS 
implementation on the server does not need to know anything about the state.

My problem is that the client application produces bursts of independend web 
service calls to the same web service. The user can load a file where elements 
are stored. Some of those elements are converted using a web service depending 
on their type. Because of the system architecture the module which wrapps the 
RPCServiceClient and which calls the web service can not know how many elements 
are converted via the web service because the conversion of each element is an 
independent operation. So until know I create a new RPCServiceClient for every 
conversion operation. Since there may be up to 5000 elements which must be 
converted in a row, 5000 instances of RPCServiceClient are created in a short 
period of time and I run into the described ressource problems with the sockets.

My concerns are that I keep a living static instance of RPCServiceClient during 
the whole lifetime of my application which may never close open ressources. So 
my question is what I have to do when I reuse one instance during the lifetime 
of the application. Is it important to initialize and close the instance for 
each call or can I just create and initialize the instance once and then reuse 
it without using any special method?

I hope this helps to understand the problem.

Thanks
- Marc
