Flex 10 mac flapping on default vlan from internal VC mac

Hi,
Config
2 x flex 10 VC ethernet switches
connected to 2 x 3750 cisco switches with 4 port channels. port channels do not cross VC modules
We are seeing mac address flaps on the cisco switch from the mac address of the internal VC stacking connection.
Is this normal ?
