I have a Remoting Class as a Singleton

<configuration>
   <system.runtime.remoting>
      <application>
         <service>
            <wellknown 
               mode="Singleton" 
               type="PTSSLinkClasses.PTSSLinkClientDesktopRemotable, PTSSLinkClasses" 
               objectUri="PTSSLinkDesktop" />
         </service>
         <channels>
            <channel ref="http" port="8901"/>
         </channels>
      </application>
   </system.runtime.remoting>
</configuration>

Its created within a "server" Service. Another client service consumes this remote object. The client is calling the remote object every .5 second using a timer (polling) (for testing)

If the server service is stopped, so the remote object is not available, memory useage for the client service keeps increasing......

I have overwritten InitialLifetimeService to return a null

public override Object InitializeLifetimeService()
        {
            return null;
        }

If a remote object is not available does .net queue all the call requests to this object??? untill all the memory is consumed? How can I dected if the remote object is not available and stop trying to call the remote method?
