[ovs-discuss] Warning Message when using DPDK

[Daniele Di Proietto]

Hi,

The warning is not particularly bad. A "revalidator" might fail to delete
a flow for good reasons (especially under heavy load).
It would be interesting to know more about the problems you're facing:

- What is your setup? (output of ovs-vsctl show)
- Are you working with OVS from current master? Which commit are you using?
- What exactly is not working? Are you trying to ping between two ports?

Thanks,

Daniele

All,
I created two servers with DPDK on ubuntu 14.04 from trunk.
I have a bridge and port configured.
But I am getting the a warning message every second on both servers.
Below is output when restarting ovs from ovs-vswitchd.log. The last
warning repeats every second.
Can someone tell what I may have done wrong?
