If HTTP URL requests are greater than 255 characters, an error in Open Database Connectivity (ODBC) logging occurs, and the request is not logged. An error is logged in the Event Log, and ODBC logging stops and then restarts, but the request has been lost.

To work around this problem, do not use ODBC logging.
