Insertion of an error report was throttled to prevent flooding of the Call Detail Recording (CDR) database

Question

Hello,
One of my Lync 2013 standard front-end servers is frequently logging this error:
Log Name:      Lync Server
Source:        LS Data Collection
Date:          28/12/2012 10:04:05
Event ID:      56208
Task Category: (2271)
Level:         Warning
Keywords:      Classic
User:          N/A
Computer:      LYNC-FE2.mydomain.local
Description:
Insertion of an error report was throttled to prevent flooding of the Call Detail Recording (CDR) database.
Component: CDR Adaptor
Cause: This is an expected condition if too many error reports of the same type were reported at the same time.
Resolution:
No action is needed. A large enough number of error reports of this type have already been inserted into the database and can be used for troubleshooting and reporting. Additional errors are not inserted to avoid flooding of the database with redundant information.

I don't appear to have any problems or issues with Lync at all. Full Enterprise Voice is in use at this site.
Anyone know why this may be occuring?
Thanks,
Ben

Did you check any additional errors? I'm seeing the same issue and linked it to this actual error message that seems to point towards a broken data model or bugged type casting/checking in the interface:
Failed to execute a stored procedure on the back-end.

Cause: Configuration issues, an unreachable back-end or an unexpected condition has resulted in the error.
Resolution:
Verify the back-end is up and this Lync Server has connectivity to it. If the problem persists, notify your organization's support team with the relevant details.
