WLC 7.5 HA - Standby keeps rebooting

I have two 5508 controllers peered up in high availability.  The problem is now the standby keeps rebooting saying it can't reach the default gateway. 

What IP would it ping with and use as the source address if the two controllers share the same IP and the primary controller is using the IPs?

How do I fix the rebooting?

(Cisco Controller-Standby) >

Rebooting as default GW is not reachable from Standby Controller

Restarting system. Reason: Default Gateway is not reachable ..

Restarting system.

I also had a LAG issue earlier so I unplugged 3 of 4 LAG connections.

As told earlier it is a known bug in WLC 7.4 which can be fixed in later versions.

WLC 7.5 HA - Standby keeps rebooting

Well they said in 7.4 that it would be fixed in the next release and I'm using 7.5.  Is it still a confirmed bug for 7.5?
