Defect Information
| Defect ID | Headline |
|---|---|
| CSCuv99982 | Hardcoded 2GB memcap for RNA (now Network Discovery) and AppId |
Problem Description
Firepower Management Centers (FMCs) that run software versions 5.4.1.4 or earlier contain incorrect memory limits. This might cause the sensor to experience high memory utilization or result in a service outage due to the sensor exhausting the available memory.
Background
FMC software versions 5.4.1.4 and earlier contain a hardcoded 2GB memory capacity for the Network Discovery and AppId portion of detection. This might result in the consumption of all available memory in the system and a service outage when the system experiences high volumes of traffic.
Problem Symptom
All available RAM is consumed and results in a service outage. The system might need to be power cycled in order to restore operation.
Workaround/Solution
Upgrade the FMC appliance to software version 5.4.1.5 or later. This software is available in Cisco Software Central.
