Jul 21, 2016
- Cisco IPS 4200 Series Sensors
Known Affected Releases
Symptom: Sigupdate fails (sensorApp aborts or is unresponsive to statistics commands) during a signature update. Prior to the failure the top utility output (from show tech) shows free memory available at 15 Meg or less. Example Top output (only 10 Meg free): top - Mem: . . . total . . . used . . . 10212k free . . . Conditions: The SSC-5 platform has 500 Meg of available system memory. The sensorApp process high memory-use condition can occur from a combination of traffic + signature-config + sig-level version + sig-updates and/or sig-tunings. If the sensorApp memory is high enough that there is only 15 Meg or less available free memory then the signature updates are likely to fail.
