In Chassis IntraCluster environment; when the Primary blade or its TMM goes down for any reason, (e.g., crash, restart, or shut down) the system posts 'IPv4 Addr collision' messages in APM logs.
Address collision is reported in the logs, and affected clients (that have duplicate IP addresses - both the original ones and the new ones) might intermittently lose connectivity.
This happens when a Chassis platform is used in IntraCluster mode with APM's Network Access.
Now the TMM leasepool IP information for the primary blade is mirrored on the oldest secondary blade, so the system no longer posts 'IPv4 Addr collision' messages.
