This is printed out for you to actually read, and take action accordingly. In many cases you just change the JOBS - line in XDS.INP to read
This message is printed if the "STANDARD DEVIATION OF SPOT POSITION (PIXELS)" is larger than the MAXIMUM_ERROR_OF_SPOT_POSITION= (default of 3).

and then continue to run XDS. In other cases you may want to change SPOT.XDS, or other keywords in [[XDS.INP]] (see also below). But in any case this is an important alert that should make you check the correctness of the parameters that describe the data collection (X-RAY_WAVELENGTH, DETECTOR_DISTANCE, ORGX, ORGY, OSCILLATION_RANGE, NAME_TEMPLATE_OF_DATA_FRAMES).

In versions up to and including Dec 6, 2010, the error message often occurs if the spacegroup is given as "0". In that case the "STANDARD DEVIATION OF SPOT POSITION (PIXELS)" from the first indexing (using 3000 reflections) is used, and not the value resulting from refinement, which takes all reflections into account. This is probably an over-pessimistic approach, and may change in future versions.
