    pRenewalTimeOption=<value optimized out>, pRebindingTimeOption=<value optimized out>, rHeap=<value optimized out>, 
    dRenewalFactor=<value optimized out>, dRebindFactor=<value optimized out>) at policy.cpp:1561

Conditions:
Occurs for DHCPv4 client requests if one failover partner is running 10.1/10.1.0.1/10.1.0.2 and failover partner is running a pre-10.1 release. Will only occur for client requests where the lease was obtained from the older release server and communicated to the upgraded server.
