Problem migrating WMS from 3.6.6 to 4.4

[Jean-Francois Doyon]

Hello,

I'm trying to migrate my 3.6.6 based WMS server to 4.4, and am running into
a glitch:

I keeps returning nothing (NOT a blank image, litrelly nothing), or, even
better, empty error messages:

<?xml version='1.0' encoding="ISO-8859-1" standalone="no" ?>
<!DOCTYPE ServiceExceptionReport SYSTEM
"http://schemas.opengeospatial.net/wms/1.1.1/exception_1_1_1.dtd">
<ServiceExceptionReport version="1.1.1">
<ServiceException>
</ServiceException>
</ServiceExceptionReport>

I'm making a very simple call:
?request=getmap&version=1.1.1&layers=places_labels_2m 

This is a labeling layer. With basic geometry, it works.  If I do geometry +
labels, it fails again as above.

The mapserver CGI I'm using draws non OGC maps fine, I've been test driving
that for a few weeks now.

I was having that problem with the micross font, but I removed it from my
WMS, replacing it with Arial.  With Micross I was getting a glyph error.

So it looks like I have yet another font problem I guess ... Could it be???

Any ideas??

Thanks,
