again ill post the MRTG of todays WAN usage... The Blue Circle is when all clients are NOT natted to SQUID we can notice that the tick didnt appear which means we have no problems with our international links.. and the RED circles indicates when clients are natted to squid box and we can notice the tick appeared at an hourly interval. at the gateway of squid we did notice that squid stops consuming bandwidth for 10 seconds then it gets up back... no suspicious stuff in cache.log neither in /var/log/messages Also this problem appeared when we our cache directories hold 100GB of objects, before that this problem didn't appear at all Waiting a reply Cordially, Bill
