Hi list,
haven´t found anything on this error in the lists, so I´d like to ask you if
it occured for anyone or someone maybe has a solution.
The error occurs when requesting a raster-layer in PNG-Format (JPEG works
slow but it gives a result). It´s not present for each raster but I don´t
see where the differentiating point could be (number of categories is the
same, both are based on GeoTIFFs). Only difference is in size (the raster
not working in PNG-Format is 48 MB, the other one significantly smaller (11
MB).
The shortenend error message from the log with the relevant parts:

Our server is running GeoServer 2.1 on Ubuntu-Linux-64 bit with Sun-JDK (JAI
and ImageIO installed).
Any clue what the reason for this behavior could be?
Thanks in advance
