QoS on Cisco ASA is being exceeded despite thresholds

I have a Cisco ASA 5510 running 8.2(1)

I have a QoS policy which limits the traffic between any server in our office to a DR server in a secondary location which limits data replication traffic to 5Mbps.  Occassionaly this is exceeded and then snaps back (assuming because of the burst rate set).  However sometimes it goes up to 8Mbps which is pretty much our entire bandwidth and doesn't come back down.

This is especially true when I set the QoS to be time-based.  I've had it set to use 5.5Mbps from 8am to midnight but then after there's no limit until 8am.  At midnight it goes to using 8Mbps but then at 8am it doesn't come back down to 5.5Mbps.  Its as if once exceeding the QoS thresholds it decides not to limit it properly.

Can anyone shed any light on what I might be doing wrong.

Thanks

I just saw the same thing

I just saw the same thing happen on my ASA. I removed the policy from the inside interface and once I re-added it to the interface it was rate limiting properly again. Did you ever figure out what was causing this issue?
