As Pete points out this unusually high 'no socket' figure could be due to packets being received for a service you don't run. Beefing up the number of PCBs you can have won't have any effect there if that is the case. Also it could be due to a socket application not binding to INADDR_ANY to pick up undirected broadcasts (they don't get delivered to interface bound ports). Of course this is probably not likely to affect your application if you're explicitly unicasting traffic. But if you intend to receive multicasts this could be the case. Are you filtering anything, or could your upstream be filtering anything?
