Severity: 3-Major


On BIG-IP Virtual Edition, if a high rate of new connections are processed over SR-IOV interfaces and traffic mirroring is enabled over a path that uses an interface with lower throughput and higher latency (such as vmxnet3 or virtio), the HA channel may experience problems leading to unexpected failovers, or failure to mirror connections.


Unexpected failovers may occur due to memory pressure in the tmm, or failures to mirror connections.


Virtual Edition HA pair with * High connections per second (will vary by size of instance) * Traffic is processed over SR-IOV interfaces * Traffic is mirrored over slower interfaces (vmxnet3 or virtio for example)


Perform mirroring over a high performance path such as another SR-IOV interface.
