*Infrastructure* Running juno on ubuntu 14.04 with GRE network using 2 network nodes without DVR. There are around 200 dhcp namespaces created on each network nodes(dhcp_network_agents=2) which has 16 cpu and 32 gb.
*Issue:* Network nodes are idle (top shows 99% idle CPU)but load average is *70-100* for a network traffic of 100-200 Kbps. I am not able to figure out why the load average is too high for an idle server with less than 100 Kbps (including my current ssh session) there is no impact for the instances but these numbers are worrying. *some observation:* CPU time spend on user space is 0%, kernel space is 0.1%,io wait is 0%,swap usage is 0%,and there are a lot of free RAM,No zombie,No process in un interruptible sleep. any idea why load average is very high?
