Invalid Pointer Operation when close WebServer Api

Hi, I need your help. I am working with new project implementing Mormot Server with Interfaced Based Method register with

var
aServer: TSQLRestServerDB;

...
aServer.ServiceRegister(TReservas, [TypeInfo(IReservas)], sicPerSession);

All is working OK except when close server. In that moment I receive Invalid Pointer Operation Error.

This is my log

Re: Invalid Pointer Operation when close WebServer Api

How do you destroy the server instances?

Re: Invalid Pointer Operation when close WebServer Api

This is my variable definitions

    /// the associated database model
    aModel: TSQLModel;
    /// the associated DB
    aServer: TSQLRestServerDB;
    /// the background Server processing all requests
    aHTTPServer: TSQLHttpServer;

Destroy:

  FreeAndNil(aHTTPServer);
  FreeAndNil(aServer);
  FreeAndNil(aModel);

Re: Invalid Pointer Operation when close WebServer Api

I found the problems. We register one services using sicShared and in the destructor in the services class detect the problem. No problems with Mormot, its was our error.

Thank´s.
