static arp doesn't help, unfortunately.

This is the output I get when the realserver loses the MAC-address of the
gateway:

rs6:~ # tcpdump -i eth1 -n
tcpdump: listening on eth1
08:06:14.062739 212.12.37.71.80 > xxx.xxx.xxx.xxx.1479: .

And yes, this happens even after applying the hidden patch. I patched all my
kernels yesterday, but the problem remains: 4 realservers do just fine, 2
cannot find the gateway after a while.

any ideas?
