High consumption of CPU after upgraded to 11.6.0

I quoted the F5 response at the bottom of this post. Since we haven't seen any latency through the F5, I'm going to consider this a non-issue for now. I'm still waiting to hear back as to why it is taking so long to pull up the Security event logs:

From F5 support:

"Hi Shane,

As we discussed, the graphs under Statistics > Performance > System CPU Usage > View Detailed Graph, will show you CPU utilization per core an what you'll see is that just Core 7 is running high and thats probably due to learning mode being enabled.

The other issue is a memory leak ramp caused by monpd which you already knew about.

So basically as long as Core 7 doesn't stay pegged at 100% for hours then the box is running within spec."
