Aug 15, 2020
- Cisco ASA 5500-X Series Firewalls
Known Affected Releases
Symptom: High CPU is seen on LINA when flow offload is enabled. It is observed that the amount of traffic through the device may be well within the limits; however, LINA CPU spikes as high as 90+ with a very small fraction of device connections made. CPU looks to be consumed most by functions that are responsible for flow offload. Conditions: FIrePower Chassis with flow offload enabled (static and/or dynamic). LINA CPU is high in spite of the cumulative traffic being within device limits.
