bonding adapters with adaptive load balancing causing IP conflict ?

I don’t think this is really a problem more of a question and sanity check.

I have bonded the adapters on my readynas with the Adaptive Load Balancing.

All has went well and to be honest i noticed the speed increase.

I have also noticed on my router the alerts for duplicate IP address conflict every so often with the two bonding mac addresses

Is this save to ignore or is it something i need to investigate.

I have a netgear switch that can support LACP as an alternative, I choose adaptive because it was a two click solution.  

any feedback ?
