[mapserver-users] Problem rendering multiple layers

I have created a simple map with two layers with shapefiles as the
datasource. I have two servers I am using for testing in order to
attempt to identify the source of a problem I am having when I attempt
to render the two layers.
Server A is running Ubuntu 9.04. It has been patched to the latest
releases. I did *not* add the UbuntuGIS repo. I installed the package
cgi-mapserver and mapserver-bin (along with the appropriate
dependencies). MapServer version 5.0.3 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG
OUTPUT=WBMP OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE
SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER
SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=FASTCGI
SUPPORTS=THREADS SUPPORTS=GEOS INPUT=EPPL7 INPUT=POSTGIS INPUT=OGR
INPUT=GDAL INPUT=SHAPEFILE
I then render my map from my browser (Firefox 3.6.17 and Chrome
11.0.696.65) with the following URL:
http://10.10.10.86/cgi-bin/mapserv?mode=map&map=mapdata/ccc.map&LAYERS=county,water&TRANSPARENT=true&SERVICE=WMS&VERSION=1.1.0&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&FORMAT=image%2Fpng&SRS=EPSG%3A4326&BBOX=-122.41859552788569,37.48140447211431,-121.56140447211433,38.33859552788568&WIDTH=450&HEIGHT=450
<http://10.10.10.86/cgi-bin/mapserv?mode=map&map=mapdata/ccc.map&LAYERS=county,water&TRANSPARENT=true&SERVICE=WMS&VERSION=1.1.0&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&FORMAT=image%2Fpng&SRS=EPSG%3A4326&BBOX=-122.41859552788569,37.48140447211431,-121.56140447211433,38.33859552788568&WIDTH=450&HEIGHT=450>
The resulting image is rendered at 450x450 and displays both the county
and water layers as expected.
Server B is running Ubuntu 10.04. It has been patched to the latest
releases. I *did* add the UbuntuGIS repo. I installed the same packages.
MapServer version 5.6.6 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP
OUTPUT=SWF OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE
SUPPORTS=ICONV SUPPORTS=FRIBIDI SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT
SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER
SUPPORTS=SOS_SERVER SUPPORTS=FASTCGI SUPPORTS=THREADS SUPPORTS=GEOS
SUPPORTS=RGBA_PNG INPUT=EPPL7 INPUT=POSTGIS INPUT=OGR INPUT=GDAL
INPUT=SHAPEFILE
I then render my map from the browser as before with the following URL:
http://10.10.10.105/cgi-bin/mapserv?mode=map&map=mapdata/ccc.map&LAYERS=county,water&TRANSPARENT=true&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&FORMAT=image%2Fpng&SRS=EPSG%3A4326&BBOX=-122.41859552788569,37.48140447211431,-121.56140447211433,38.33859552788568&WIDTH=450&HEIGHT=450
<http://10.10.10.105/cgi-bin/mapserv?mode=map&map=mapdata/ccc.map&LAYERS=county,water&TRANSPARENT=true&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&FORMAT=image%2Fpng&SRS=EPSG%3A4326&BBOX=-122.41859552788569,37.48140447211431,-121.56140447211433,38.33859552788568&WIDTH=450&HEIGHT=450>
The resulting image is rendered at 740x400 and is a single white image
(no layers rendered).
If I only include one layer at a time the specified layer *does* render
(again at 740x400 *not* 450x450 as specified in the URL). If I change
the parameters &LAYERS to &LAYER (singular) and use two (one for county
and one for water) the two layers render, again at the wrong resolution.
I'm completely stumped. I've been using mapserver for a number of years
now, but I hadn't upgraded to 5.6.6 as I'd been using it on my ubuntu
9.04 server. I'd love to take advantage of the changes available in
5.6.6 but right now I can't seem to get any of my maps to work. Help!
I have enabled debugging for both servers. The output for Server A when
requesting to render both county and water is:
