Make the tcp_backlog error message clear

Browse Source 
The tcp_backlog is used when there is not process running to accept a new connection, but it is limited by the number of allocated backlog containers. The current error message induces the user to believe there is not free memory to allocate a new container, but actually the containers were allocated during the initialization and were available until the last element of the list has been removed to use.
