I believe this is some kind of Dos Attack from some virus on client's systems because when this happens, MRTG shows increase in HTTP all service time and HTTP miss service time (I am also attaching MRTG graphs for your view) and all the clients start complaining. Can any one shed more light on this problem? Like which virus is responsible for this and what can be done in squid config to avoid this except to block/disconnect the infected client. � Regards Mahmood Ahmed Senior Network Engineer Buraak Telecommunications Pvt.
