Content Gateway error indicates too many network connections

By default, Content Gateway supports 8000 network connections: half of this number is allocated for client connections and half for origin server connections. A connection throttle event occurs when client or origin server connections reach 90% of half the configured limit (3600 by default). When a connection throttle event occurs, Content Gateway continues processing all existing connections but does not accept new client connection requests until the connection count falls below the limit.

Connection throttle events can occur under the following conditions:

If there is a connection spike - if thousands of client requests all reach the proxy at the same time. Such events are typically transient and require no corrective action.

If there is a service overload - if client requests continuously arrive faster than the proxy can service them. Service overloads often indicate network problems between Content Gateway and origin servers or indicate that Content Gateway needs more memory, CPU, cache disks, or other resources to handle the client load.

Examine the Performance graphs to determine the nature of the connection throttle. In particular, check the Client Connections, TCP Connections, and Client Ops Per Second graphs. You can also check error messages in the system log file, error log file, or event log files.

If necessary, you can reset the maximum number of connections supported by the proxy on the Configure > Networking > Connection Management >Throttling tab or by editing the value of proxy.config.net.connections_throttle in the records.config file. Do not increase the connection throttle limit unless the system has adequate memory to handle the client connections required. A system with limited RAM might need a throttle limit lower than the default value.
