Panic in vxlan_get_route() after enabling ipfix on openvswitch bridge

Solution Verified - Updated -

Issue

  • We are setting up an Openshift environment on RHEL 7.3. However, to be able to get some insight into the network aspect of the environment, we need to do some flow exporting. However, when enabling IPFIX exporting on Open vSwitch towards a IPFIX collector over UDP the system crashes after a random period of few seconds to several minutes.

Environment

  • Red Hat Enterprise Linux 7.3
    • Openvswitch
    • vxlan
    • Ipfix
