Hello, I am using OVS-1.7.1 on embedded Linux (kernel-2.6.32.27). I am generating traffic at high data rate using 'netperf' and I get the following warnings:

Is it normal for OVS to show these warnings/information messages when dealing with high data rate traffic? Is there a way to hide or minimize them? Regards. - Farrukh Aftab Khan
