Perhaps the traffic on your network is high enough that it is delaying the echo request or reply enough to cause the connection to be dropped, or perhaps NOX is too busy to reply to the request promptly. You can always increase the timeout interval to whatever works best for you, or disable the fe

Hi I was running OVS (ovs-1.1.2 in kernel mode, on a core i7 machine with 4GB of RAM) under several Gbps of load. I noticed some unexpected behavior; OVS would disconnect from Controller (NOX 0.9 zaku) under heavy load conditions and re-establish the connection when the load was reduced (the behav
