Symptoms

On a system with a lot of AVR related data for DoS Attacks, it might take a while to load the data needed for display on DoS Visibility pages. GUI queries the backend for all the required data simultaneously, which can cause the web server to attempt to handle too many open connections, and result high CPU usage.

Impact

Instability in GUI usage. Performance degradation. Potential disconnections.

Conditions

Large amounts of data for DoS Attacks

Workaround

None.

Fix Information

Optimizations were done both on the back-end/database side and on the GUI side. GUI will now throttle its queries to the server.
