Running forever.

What version of the Arduino software are you using? On what operating
system?  Which Arduino board are you using?
Arduino Mega2560, Ethernet shield. (Official Arduino), Arduino 1.0.1, Win7

It is hard to reproduce. Sometimes the cliet.connect() keeps returning a  false 
after a few hours, Sometimes after a few days.
I think (but i not sure) the problem occures more often if the WizNet is 
exposed to externel attempts to make a connection after opening ports on my 
router.
