Known Affected Releases

9.1(1)

Description (partial)

Symptom:
The DP-CP punt queues can become exhausted leading to packet drops if there are multiple features configured. Since these queue's are limited to the same size on all platforms, it's far easier to exhaust these resources on the larger platforms since they handle much higher packet rates.

Conditions:
Larger ASA platforms with heavy utilization of protocol inspections and URL filtering.
