[squid-users] Re: WCCP Service Flapping every 40 minutse approx

Hi Amos ,
thanks so much ,
i noted a debug on the Cisco router , and you must be correct about jitter
or something like that occurring between the router and the squid server .
note that is only 1 Giga Ethernet link between squid and router as full
duplex with speed 1G
===========================================
i could gather some logging from router when the wccp lost .
as u see , it seems like hello messages every 10 seconds
here is a sample logs :
plz open eyes at the bold lines , it seems the time where the wccp service
is lost .
