Greetings,
The first thing that you may want to check is to ensure you have enough disk space on the particular drive that you are logging to. This could be the direct cause if you are running out of HD space. Assuming that this isn't the case, I would check to see if you have any deadbands set up on the tags or if the deadbands are set to zero for the tags you are logging. The logging buffer could be overflowing if the tags are constantly changing and DSC is trying to log all values. Lastly, check and make sure that the tag engine is still running at the time you receive the error message. If it is, open it up by double-clicking on the icon in the system tray(in the bottom, right-hand corner of Windows, by your time) and make sure that "log data" is still c
hecked. Hopefully the solution will present itself by checking these things. Have a good day.
