Known Affected Releases

16.10.1

Description (partial)

Symptom:
In Azure, CSR1000V occasionally experiences high traffic latency.

Conditions:
The problem exists logically in that space between Linux networking stack delivering the packets to CSR1000V for them to be processed. The high latency traffic issue is more likely to be hit with larger vCPU sizes. In the meantime we have a proposed workaround which fortunately can be done to the existing CSR1000V instance but unfortunately will not be sticky.  Any reloads of CSR1000V will require the same workaround be applied again.
