Event ID 4133 & 4376 MSExchangeRepl

Hi

I have an Exchange 2013 DAG with 2 Servers and created a database "DB01" with an active copy - no issues

After creating a further 9 Databases, the Application Log is full of Errors, repeating every 15 minutes:

4133 Database one datacenter health check failed.

4376 Database one datacenter available copy health check failed.

When I run Get-MailboxDatabaseCopyStatus, all Databases are Mounted and Healthy

When I run Get-MailboxDatabaseCopyStatus | fl the only differences between DB01 and the other Databases are:

DB01

ActionInitiator                       : Unknown

LatestFullBackupTime                  : 31/01/2014 23:17:05
SnapshotBackup                        : True
SnapshotLatestFullBackup              : True

DB09

ActionInitiator                       : Service

LatestFullBackupTime                  :
SnapshotBackup                        :
SnapshotLatestFullBackup              :

All Databases have been successfully backed up (Full and Incremental)

Why I am seeing errors for the additional Databases?

Thanks
