Where do I fix: undisposed object --check module destructor?

[alanxptm]

I have finally finished my project, but every time I end the simulation I get messages about this in the console:

undisposed object: (InternalMessage) Net.intG[1].intPeer. -- check module destructor

I guess that it must be because I keep messages in several buffers, which is part of the simulation, but I ignore if leaving them like that its a problem for my system once the simulation has been finished and Omnet closed, or a warning just in case. The docs info says:

• Destructor:

  Delete everything which was allocated by new and is still held by the module class. With self-messages (timers), use the cancelAndDelete(msg) function! It is almost always wrong to just delete a self-message from the destructor, because it might be in the scheduled events list. The cancelAndDelete(msg) function checks for that first, and cancels the message before deletion if necessary.

OMNeT++ prints the list of unreleased objects at the end of the simulation. When a simulation model dumps "undisposed object ..." messages, this indicates that the corresponding module destructors should be fixed. As a temporary measure, these messages may be hidden by setting print-undisposed=false in the configuration.

My questions are.. Where the module destructor is or do I need to implement it? How do I implement that? and How do I know which objects do I need to dispose?

I've created the finish method with a buffer cleaner but now I get an error exit when I terminate the simulation as if it just crashed

void Peer::finish(){
    if(!buffer.empty()){
        for(int b = 0; b < buffer.size() || buffer.empty(); ++b){
            delete(get<0>(buffer[b]));
            buffer.erase(buffer.begin() + b);
            b--;
        }
    }
}

Is it possible that you have a message that you use for creating a timer?

No, but I've found that it's becuase I was creating msgs and not deleting them after being sent. Thank you, I've created an event now and took care of that.
