Since my upgrade from xen 2-testing  to xen 3-testing I have the problem
that domain0 consumes more and more memory on domU networktraffic.
It is about 50 bytes per packet that gets lost.

I reproduced the bug on another machine.

In normal bridged setup all works fine.

I changed the setup in the following way:
- added an ip address to the bridge (in another subnet (B))
- changed domU ip address to a net B address
- added masquerading for eth0 in the postrouting-chain in dom0

After that I pinged a host outside this machine.

Sending and receiving 100.000 pakets results to a
dom0-memory-consumption increasement of about 5 MB!

I have to restart this machine once a day for not running out of memory.

What can I do?
