This is what happens. When I send i.e. 500 ping packets inside my network, not going through the router -> no packet loss. Everytime I go through that interface, I get 1-2% ping packet loss.
I am lost for ideas. I thought it might be a buffer problem, but they look ok. Could it be that there are just to many packets for the interface to handle?!

Hi, the interface is significantly loaded, but not excessively yet. Packets could be lost on another link beyond the 7200, you should do aimed pings to track where exactly it happens.
Also note that ping reply is a low priority task for routers, so it is normal that some reply is lost when pinging busy routers.
