Severity: 3-Major


TMM CPU/Memory utilization keeps increasing unchecked under steady, high SIP traffic.


System resources are regained once load reduces, but having load remain high for a long time eventually results in SIP call failures.


This occurs with steady, high SIP traffic levels for a long duration on a SIP MBLB profile with call-id persistence.



Fix Information

TMM CPU/Memory grows in accordance with the connections. If the SIP connections remains steady, resource utilization remains steady, as expected.
