I notice that you are talking about only one F5? How do you have your secondary F5 configured?? Perhaps the issue is in that?
Granted, I realize this doesn't contribute to the conversation, but it does raise a point.
Just saying...

Given, I run a smaller environment, but even on a several-years-old v2.2.x install I regularly see several thousand requests per second -- not minute -- with tons of logging enabled -- handled while hardly touching the CPU. Are you sure you really need multiple machines?

Sorry, it is an F5 cluster, two 6400's in active<->active mode. We also tried active-passive mode, with no change in the issue.

The environment uses an active-active cluster of F5 Bigip's (6400's). We tried in active-passive mode with no change in results
