Comment 1 for bug 1400617

This error message is logged by the contrail-collector when the vrouter-agent sends invalid uuid string. In this specific case, vrouter-agent seem to have sent empty string for nw_ace_uuid in the flow log. Assigning the bug to Ashok to check if the vrouter-agent sends "" nw_ace_uuid in any case.

As far as the high cpu utilization is concerned, there is not enough information to analyze further. Perhaps, it could be due to high rate of messages sent by the agent/other generators. Any information regarding the number of generators connected to the contrail-collector and the rate at which the contrail-collector received messages during period of high cpu utilization would be helpful.
