I have seen nothing but obscure random routing issues on this gold star release:
-Default route completely dropping until devices are rebooted (believed to be related to an undocumented IP SLA bug) -dynamic routing no longer working (even though routes show in routing table) -VPN/VTI related route issues (traffic being sent out the wrong interface).
Cisco TAC has been ineffective, and has not been able to identify any fixes other than to reboot the device and take a longer outage. These issues started a few weeks after upgrading the entire fleet of 200+ firewalls, not immediately.
For your own sanity, use something other than the gold star release.
