Yes do the right things.. (I think...) . The checks recognize well when 
a server goes down. In the list doesn't appear, but the packets are 
thrown to the serve many minutes later. I then the packets are thrown to 
the "limbo" (/dev/null I think..). I don't know what is happen but in 
another situation with a firewall maked with Shorewall, I had a similar 
problem. I changed the rules in firewall (one port for another) and the 
packets was ruled to the first port. I reboot the machine and all OK. 
With TCP this not happens never.

It's strange.
