Description (partial)

Memory is leaked during session tear down. The following error message is logged to the console after the address space limit is exceeded.
on standby-ESP:
 %CPPDRV-4-ADRSPC_LIMIT: F1: cpp_cp:  Address space limit

When a policy with conditional policing enabled is removed, the traffic manager leaks 16 bytes of resource DRAM per target. The leak increases exponentially when tearing down more than 20000 PPP sessions. Though the system may still be operation, the control plane performance becomes severely degraded causing subsequent configuration processing to become very slow.
