Opened: Apr 02, 2018
Severity: 3-Major

Symptoms

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.

Impact

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

Conditions

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)

Workaround

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

Fix Information

None
