> But it just doesn't happen always, it seems to be related to context startup
> becouse when it happens it happens every time, but when it starts and you get
> no errors it will not raise the exception ever.
> So I think this should be a problem with model loading or something like
> that, I will try to attach the model causing the issues but in anyways when
> the error occurs is when we are creating a SessionLogApi object that inherits
> (shared table inheritance) from an abstract class SessionLog.
> The same commit has another new object of class Session that is related to
> SessionLogApi so Session object stores SessionLogApi id.
> Please ask me for any extra information you need to identify the error, I
> will hapily provide it.
