On Oracle Communications network Charging and Control (NCC), 5.0.1 version, Prov IF

It is observed that Provisioning Interface (PI) is not able to handle overload situations.

During an outage there appears to be no HTTP failure responses from the PI. All requests are handled, and all requests are successfully replied to. The PI was doing its job and limiting incoming requests. Currently PI is configured with 16 ports @ 35 Max Connections. The issue is that under this load PI responses were slower than usual, and that connection requests were rejected at the application level as the PI had 35 total connections per port. During this period the PI was responding to incoming connection requests with a rejection "TOO MANY CONNECTIONS" message but taking up to 7 seconds. The PI responding to incoming connection requests with a rejection "TOO MANY CONNECTIONS" message can take 7 seconds!

This is too long and is causing the connecting system to retry making the number of connections worse.

Is this a fault in the PI that it is not able to handle overload situations? Can one increase max connections or the number of ports for fixing this issue?
