Core issue

Cisco bug ID CSCsb60583 documents this issue.


When you run a Cisco 2800 Series Router at high CPU utilization, the I/O memory begins to decrease until all memory is exhausted. At this point, the router begins to report Pool Manager tracebacks.


This symptom is observed on a Cisco 2811 or Cisco 2821 that uses the onboard VPN crypto engine. The symptom is prominently observed when crypto is configured over serial interfaces.
