Do you need persistence? If not, turn it off. If you do, then for a rolls-royce solution you need an iRule that tracks the sessions by pool member and notes when they move to the 'standby' unit and moves them back.

 

 

Or track persistence by JSESSIONID. Then a new JSESSIONID will have a chance of being balanced back to the pool member that just came up. I'd probably switch to least connections too...
