We are an issue, related to the metadata cleanup. Some time ago we reduced the retention period down from the default to 3 days and did not encounter issues, then last suddenly began to encounter the error below for various publications. It does not occur on
every synchronisation. The output from setting agent parameters defined at http://msdn.microsoft.com/en-us/library/ms151872(d=printer,v=sql.100).aspx is
shown below

restart the synchronization with verbose history logging and specify an output file to which to write.
