SEPM Server sending huge bandwidth

Hi, The SEPM server for one of our customers is sending out about 7-8 Mbps of bandwidth for a couple of hours now. It is not one client that is pulling that much bandwidth but about 7 or 8 clients pulling at once.  It varies between 10 Mbps and 30 Mbps. It is all being used in the Apache Webserver and I have tried to restart the Symantec Webserver service and the Symantec Manager server but when the service comes back up and all clients reconnect, it starts again. I have also changed communication setting from Push Mode to Pull Mode.
