diameterControlAgent Crashes if GGSN Continues Sends Requests for Invalid MSCC Session (Doc ID 2082003.1)

Last updated on MAY 25, 2018

Applies to:

Oracle Communications Network Charging and Control - Version 4.3.0 and later
Information in this document applies to any platform.

Symptoms

In all versions of Oracle Communications Network Charging and Control (NCC), a problem exists in the diameterControlAgent process where it can crash (due to a Segmentation Fault (SEGV)) if a Gateway General Packet Radio Service (GPRS) Support Node (GGSN) continuously tries to request more units from a MSCC sub-service which the diameterControlAgent has already released.

The following error may be seen in the diameterControlAgent.log just before it crashes:

Oct 24 16:27:15 slc01 diameterControlAgent: [ID 675952 user.error] diameterControlAgent(24958) ERROR: {960210} TCAP_PRE_END received in state ACSent, Session-Id=UGW1UTB_gy;3654691831;210;4174, Charge key = 555

Changes

Possible integration with new GGSN or some new type of DIAMETER traffic is hitting the diameterControlAgent.
