ASA-5520 CPU goes to 99%

[Geze2498]

i have two ASA-5520's working in active active mode at the Edge of the LAN both working at a throughput of 300 Mbps. the problem i faced is that the CPU goes to 99% in peak hours and roughly over 50-60% in off peak hours. the ASA's are operating independently but the problem is the same on both sides. Dispatch Unit contributes to 75-80% of that CPU usage and about 15-20% is Logger.
is it normal or is there any fix for it?

Thank you.
