Please help us to help you by giving a more complete description of the problem --

What database are you using?  Which version, service pack/patches?

What version of ArcSDE are you using?  Which service pack and/or patches?

What ArcSDE client are you using to pan & zoom? Which version, service pack/patches?

What geometry storage type are you using?  What does 'sdelayer -o describe_long' report?

How did you populate the data?  What does 'sdetable -o describe' report for the table? 
Has this never worked, or did the failures start recently?

Have you received any relevant database error messages recently?

The error is the result of an invalid MDSYS.SDO_DIM_ELEMENT. Refer to the Oracle documentation for more information about this parameter.

Solution or Workaround
Change MDSYS.SDO_DIM_ELEMENT Extent values based on Oracle calculations or a best guess. You can use the Oracle tool SDO_TUNE.EXTENT_OF to determine the minimum bounding rectangle of the data in a layer.
this is the link about the detail:http://resources.arcgis.com/content/kbase?fa=articleShow&d=15673
I thought that this is happen when the user change the project of layer by affine transformation which make the geometry change too much.This may lead to the spatial index didn't work.


I hope this could help you!
