remoting client hangs

I have a remote programm (serveractivated singleton) that logs several actions from an other application (logging has to be synchronous) The logger is the server and the app to log is the client My problem is when i close the logger/server the application/client hangs itself because it waits about 1-2 seconds for each try to log something (and it logs up to 3xx times a second)) If i realize that with synchronous threads after a short time the count of the threads increases so high that it causes an memory error Is there a possibility to send something without waiting for an answer from the server? I tried to use [OneWay] attribute but that didn't work (i read somewhere that it is only for asynchronous methods ?!) Does someone know how to solve this problem ?
