Did you properly initialize your timer? You need to construct your  
timer in the element constructor, and then in the initialize method of  
your element you need to initialize it using  
Timer::initialize(Element*).
Doing no packet processing in an element will have no effect on this,  
it is perfectly possible to have a routing table that is just an  
infobase element while maintaining timers.
