AskTimeoutException: Timed out - Play Framework 2.1

I'm developing a metaheuristic algorithm in Play framework and must have an indefinite timeout. After an hour of loaded I get the following error:

[AskTimeoutException: Timed out] 

! @6g40d7af9 - Internal server error, for (GET) [/planificar] ->

Is there any way to fix this problem?. Thanks.

EDIT:

This is my Controller

public static Result planificar() {
        Carga.cargarGlobales();
        Moacs moacs = new Moacs(cargarParametros());
        moacs.ejecutar(); // metaheuristics algorithm
        List<Solucion> soluciones =  moacs.getConjuntoPareto();            
        return ok(soluciones);
    }

You should make this an async controller: http://www.playframework.com/documentation/2.2.x/JavaAsync

You could set Timeout to a very large value. From Scala documentation, the range of FiniteDuration is limited to +-(2^63-1)ns, which is roughly 292 years.

For example, one could do this:

(someActor ? someMsg)(365 Days).map { x => .... }
