Golang rpc call resolve unexpected EOF

Question

I am getting an unexpected EOF error after the execution of Call function in client code.I have a tcp server listening on port 8081 and have defined custom format for RPC request and response type.

Client Code

    c, err := rpc.Dial("tcp", "127.0.0.1:8081")
    if err != nil {
        fmt.Fprintf(w, "Tcp Connection Error")
        return
    }
    defer c.Close()
    response := new(Result)
    err = c.Call("Profile.Manage", msg, response)
    if err != nil {
        fmt.Println(err)
    } 

Server Code

    handleobj := login_change.NewProfile()
    rpc.Register(handleobj)
    PORT := "127.0.0.1:8081"
    l, err := net.Listen("tcp", PORT)
    if err != nil {
            fmt.Println(err)
            return
    }
    defer l.Close()
    rpc.Accept(l)

Common Package

type Profile struct{}

func (h *Profile) Manage(b Msgobject, res *Result) (err error) {
    res.Message = "Control reached"
    return nil
}

func NewProfile() *Profile {
    return &Profile{}
}

It's resolved now,I was actually trying to perform operations on a variable which was initialized by a different process thus resulting in this issue.
