[mapguide-users] Grey image after some time in MGOS 2.0

[Maksim Sestic]

This is a common problem with Autodesk MapGuide Enteprise 2008 and Autodesk
Raster provider. Happens most often if you have several layers within base
layer group. During base layer tiling operation it happens that some tiles
simply get "skipped", and stay that way (cached as "empty" tile) even after
MapGuide service gets restarted. I hope Autodesk will get this fixed in 2009
version.
