Description (partial)

Symptom:
aaamgr going to warn state for memory usage.
aaamgr segmentation fault

Conditions:
If RADIUS accounting is configured via 'mediation-device context-name <context name>', the following configuration must be set on the APN.

apn <apn name>
  accounting-mode none

instead of:

apn <apn name>
  accounting-mode radius-diameter


When RADIUS accounting is configured via 'mediation-device context-name <context name>', and 'accounting-mode' is set to 'radius-diameter', this results in a memory leak of accounting session list in aaamgr causing a stack overflow which results in the aaamgr crash.
