Is the server on that same VLAN, i.e. do you have to route to get to the server? Are you do you have an S series core? Have you put a port in that VLAN and run wireshark see if there are any traffic anomalies? Have you done a port mirror on a phone to verify that to COS is being set? How frequantly do you see the issue? What tools do you have for monitoring? We found a MIB for non-unicast traffic that has helped us track down a source for broadcast packets in the past. We ended up applying a limit per port for broadcasts to stabilize our network.
Sorry for so many questions. Feel free to call if you want to talk off line. I'm very curious.
