Re: [Geoserver-users] ImagePyramid. Tiles sometimes drawn and sometimes missing

[Simone G. <sim...@ge...>]

Ciao Russell,
the suggestion from Andrea might be correct, although I see you do addo
with average interpolation (hence I don't think you have paletted images).

It would be help out to have the following:

-1- the mosaic.properties for the incriminated level
-2- the output of the gdalinfo on one of the files for this level
-3- a longer portion of the log that shows exactly from where this error is
thrown.
