ASA HA pair generating invalid source MAC 00:00:00:00:00:00

We have ASA pair installed and connected to C4507 switches.

Here the error log in my C4507R switch.

"*Aug 7 20:58:51.850: %C4K_L2MAN-6-INVALIDSOURCEADDRESSPACKET: (Suppressed 26 times)Packet received with invalid source MAC address (00:00:00:00:00:00) on port Gi7/17 in vlan 931"

The repective connected interface is link to a HA ASA Firewall.

Any idea? Thanks!
