In the distributed application I have written, I used the server-side Singleton's activation method, but when there is a client, it is found that the memory usage of the server is increasing, and does not decrease, direct memory usage. Close the client-side memory usage is not reduced, only the server-side program is turned off, and the amount of memory is reduced. I don't know why this is this? ?
