OpenTP1 secures the internal management table according to the value specified in the max_socket_descriptors operand. Specifying a larger value in the max_socket_descriptors operand causes OpenTP1 to secure a larger malloc area.

Also, when temporary closing is started, the malloc area is secured for managing the sockets that are being temporarily closed. After a response to the temporary closing request is received and the socket is closed, the malloc area is released when the socket is reused by another connection.
