I get lots of those from time to time. It's usually when the server team is installing a new virtual server on a VMware host. On VMware, each virtual server has its own individual MAC address. If you create a new server, it generates frames from 00:00:00:00:00:00 until it has been correctly configured.

Do you have a VMware host or something similar on that port?

Yes, we have ESX servers that has wmware hosts. But the port is not WMWARE host. It is normal Linux server. Syslog message comes to 5-6 switches to trunk ports at same time.
