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.
