Guys I'm having this very weird issue  with just one of the servers.

I have two servers set using, WCCP2 with 3 Routers, each router shows 
the same log, both server have the same Service ID, every 40 Minutes 
only one of them shows lost to the routers but SQUID nevers goes down?

Could you send me any Idea?

Thanks
