We have also encountered this problem with the favicon when APM is active on a virtual server.

We run a productive webshop where single URI Pathes are protected by APM.
For this the APM is switched on in the VS as well as an iRule that ACCESS::enable only the specified uri paths.
Everything else is default ACCESS::disable

This works for all requests, traceable in the LTM log, but especially /favicon.ico is still stopped by APM and the requests do not reach the LTM Policy.

Looks like a Bug from my view.
