I recently upgraded the IOS on my 4507Rs with SUP-IV from 12.2(31)SGA10 to 12.2(53)SG. Since I did that I've been seeing this log message pretty frequently:
%C4K_SWNETFLOWMAN-4-FLOWSTATISTICSLOST: Flow rate too high. 545460846592 packet byte count statistics update lost {IpSa: 0.0.0.0}{IpDa: 0.0.0.0}{IpProt: IpProtocolNull}{IpL4SrcPort: 0}{IpL4DstPort: 0}{RxVlanId: 0}
According to this link:

The message is informational only, but I wonder why It's only started to appear since I upgraded the IOS. Also, I've noticed significantly higher CPU usage as well.... like 90-95% vs the ~70% I saw before. I think I will open a TAC case about CPU usage, but thought I'd ask here if anyone knew anything about that log message. Thanks!
