If there are files being go to Configure-System Errors to see what Data Log error is causing the data buffering.ĭata from the buffered files will be the first to be processed and must be resolved to move onto the next set of data, so current data will not be able to be logged until the store and forward buffered files can be processed. dlb files are being buffered for the logging group. When there is an unresolved error data will be buffered to the Store and Forward directory specified under Configure-Options-Store and Forward.Ĭheck the directory specified for the store and forward location to see if any.
