CSCvb30960 - Large flow introduces latency on all traffic in FirePOWER Service on ASA

We are experiencing latency issues on an ASA5515 with the FirePower module and software version 6.3.0.2-67.

This issue started at 0300 UTC on the 5th June with both the CPU's jumping up to 90%+ and we experience a latency of between 500-1600ms for traffic being inspected by the Module. 

 

Has anyone else experienced this issue with this version and module?

hello, you need to understand elephant flow, see the IAB rule concept.
