Surge Queue Buildup
When a server receives a surge of requests, the server becomes slow to respond to the clients. Often, the overload also causes clients to receive error pages. A virtual server needs to have enough back-end servers configured to handle the incoming requests.
Using the Surge Queue Buildup indicator, you can view the virtual servers that have surge queue buildup. Click the Surge Queue Buildup tab to view the issue details.
The Recommended Actions to troubleshoot the issue are:
Increase the number of client connections limit. For more information, see Set a limit on the number of client connections
Increase the back-end servers to serve the application requests
