Hi,
On ASA 5510 8.2.5(50)
We are contantly gettin high cpu usage for Dispatch unit process for last 10 hours. The Dispatch unit is taking approx 40% usage constantly.
We checked teh following:
1. The interfaces.
No error counts, overruns, underruns reported.
2. show perform
All connections below normal/avg. values
3.show conn and xlate
Approx 1100 and 112
4. show traffic
shows very less drop counts ( max is 3 pkts/sec) on some interfaces not all.
Traffic usage is very less . Approx 4Mbps from all interfaces cumulatively.
5. Checked inspections.
No drops in global service policy [ only global is there]
