w5500 problems

Hello!

I use wiz850io modules with xmega256a3u. My app connects to a server, listening at 8013 port. A special 'protocol' to transfer data and maintain TCP session is made. Everything works fine, but then a TCP retransmissions start to ocure.
After a few houres wiz module draws so much current, it couses my 0.5A DC/DC switcher to 'crash'.

Server is at 10.10.2.241, the two wiz+xmega boards are at .242 and .243

I did not attach my code jet. Here is a wireshark result. Does anyone encountered problems with w5500? (yes, I have checked at least 3 forums, Mark already gave me some help a few weeks ago about w5500 lib...)

Thanks!
