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

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
