Cisco ASA 5520 failover

Hi All,

Please can someone help with a failover issue that I ahve and Ijust cant get my head round it..

I have two sites connected via 10G LES link and I have a Cisco ASA 5520 at each site. One of the Sites is the DC and the other is our DR site.

I have configured failover for the Cisco ASA firewalls and would like the node in the DC to be the active firewall. However when I make the the DC node the active firewall it keeps failing over to the secondary node at the DR site. I have changed the failover parameters from milliseconds to seconds and even used the maximum parameters in terms of polling and failover but I still get the same issue. I have also stated that failover should occur if 50% of the interfaces fail, but that too has not solved the issue. We have plenty of bandwidth between the two sites (10Gig) so i dont understand why the firewalls keep failing over. I have tried many times to manually force the node in the DC to be the primary active one but it kjeeps failing over to the DR site.. The Interface used for the failover is a gig interface; I have a separate VLAN configured on the core switches for failover and the failover interfaces are the only interfaces that reside in this VLAN..

Looking at the logs it states the follwoing:
