Hi Jesse, Unfortunately I don’t have any other logs into dmesg, kern.log and syslog. The problem is that I have a big amount of packet loss and retransmission for 25% of time. So the OVS Rule for 75% time works. It seems like a overflow kind but I’m not capable of debugging C++ code anymore. Thanks a lot for your support!

We are using Ubuntu 12.04.4 with Kernel 3.13 mirror release 11. With the latests OVS versione (2.1.2, 2.1.3, 2.2.0 and 2.3 DEV - compiled today) I have a lot of the below errors in ovs-vswitchd.log (compute and network nodes) This result in high packet loss and high latency. Could someone help me to understand better this error and maybe fix it? Below the error log and some useful informations Regards!
