Hi,
I am spending a lot of time to resolve this issue.
I run a lot of WMS requests to mapserver always on the same mapfile and
same layer.
Some time, and I don't understand why , mapserver return me the error
in the subject.
The error is localized always in a specific area , it isn't random.
Antonio,
Is the problem reliably repeatable with a particular request?
Does you have a tiled raster layer in your map file?
The error generally means that a raster file was not able to be opened
with any of the provided mechanisms. Generally speaking it should be
GDAL that opens the file, but it would seem that for some file (at least
sometimes) GDALOpen() is failing.
It may be helpful to enable GDAL debug output, especially if you can narrow
things down to a particular request the triggers it. This should be
accomplishable in the MAP file by adding this line within the MAP object:
CONFIG "CPL_DEBUG" "ON"
Alternatively set this as an environment variable in a mapserv cgi wrapper
script.
Best regards,
