Lync Server Centralized Logging Service Agent Service encountered one or more errors while converting ETL records.

ETL file path: %1   Formatting errors: %2  Missing message format(s): %3
  %4
Cause: Lync Server Centralized Logging Service Agent uses default.tmx files to convert ETL records to binary cache file records. If it can't find the message format information for a record it will be unable to determine the data types of the insert data for the record and the insert data will be lost.  This can happen if the default.tmx file is out of sync with respect to the code generating the .ETL records.
Resolution:
Verify that default.tmx files are current and update the default.tmx file(s) if necessary.  Alternatively use the TmfFileSearchPath setting in CsCentralizedLoggingConfiguration to point to a UNC path that contains additional .TMF files that will contain the missing message formats.
