Windows service memory leak problem..

Windows-service

I have developed a windows service in c#.net which is basically a client server application. Here client sends request and server looks up in the local database using a third party API. A wrapper class is used to call the function of that API. My problem is, if i run that windows service send client request in a while loop for hours the memory in increasing but if i stop the client program memory is not decreasing at all(it remains on that level). Although I have done the same thing with a console application which seems to work fine as its memory are decreasing. Then i use memory profiler(perfmon, ants) but i cannot come up with a solution. I am really confused as my console application works fine ..but windows service is not(which is basically the same code except i have written the Main of my console application on ON_Start).

*It is a threaded server, for every client I creates one thread,

*I use tcpclient class.

*In the memory profiler private bytes are increasing, but # of .net heap bytes remains the same. but, I had called that wrapper class with another console program in a loop i didn't find any memory leak. confusing thing is console application working correctly.

* I override the dispose method of that wrapper class and latter call that dispose method whenever i used that object.
