[Geoprisma-dev] The image cannot be displayed

[Yves Moisan]

Hi All,

I am experiencing a somewhat disconcerting behaviour at times that I'd
like to know if other people experienced too.  In a nutshell, I
sometimes get the following MapServer response (text output as an image
so it's gotta be from MapServer) : 

`The image
"http://somehost/gp/proxy.php?osmservice=MapServer&osmtoken=TODO%
20Delete%
20this&osmresource[]=some_resource&TRANSPARENT=true&LAYERS=some_layer&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&FORMAT=image%2Fpng&SRS=EPSG%3A900913&BBOX=-28471264.290562,-8805545.486875,28471264.290562,8805545.826875&WIDTH=1455&HEIGHT=450" cannot be displayed, because it contains errors.`

I've had the problem once with the VMAP0 MetaCarta service.  For some
reason, a GP config file in EPSG:900913 worked, but a very basic 4326
example stalled with that kind of error.  Googling around reveals the
problem isn't particularly easy to pinpoint.  It has to be an
environment thing but what exactly I don't know.  Has anyone seen such
behaviour in the context of GeoPrisma before ?

TIA,

Yves
