SOAP Client

I've been using js SOAP client from KitchenSink examples, ui/common/mashups/soap_client_library.js. My application have update every 5 min. When I update an application I call soap client with:

SOAPClient.invoke(appDataManager.userUrl, "authcheck", _obj, false, authcheckResponse);

and I have authcheckResponse callback function where I manage response from server. I repeat this for number of documents in my app which are stored on remote server, some messages etc. But every time I invoke this SOAP client my application uses more and more memory, and it never reduce amount of memory so in some moment application snaps. I need some clue how to solve this one and is this client good to be used in mobile application.

Thanks in advance.
