Seeedstudio Ethernet Shield heat dissipation

My ethernet shield goes hot after 5-10 mins and wont respond anymore using that sample of the webserver for arduino.

I am using a seeeduino v1.0 or 1.1 (not sure, 6 months old).

This is normal? I thought that this shield would work to control things remotely, but with the danger of damaging it by heat, I’m not sure now.
