<font face="Times New Roman, Times, serif">Hi everyone,<br>
<br>
I have stumbled upon something that, at first sight, looks like a bug
in Mapserver.<br>
<br>
The situation is this:<br>
<br>
I have one server setup as a WMS Client to another WMS Server.  The WMS
Server has 3 layers, which are all shapefiles.<br>
<br>
When I send a GetMap request to the Server directly, I get a map with
all 3 layers.<br>
<br>
When I send a GetMap request to the Client, I get a map with only 2 out
of 3 layers, and I can see a Windows popup on the server that says:<br>
<br>
"mapserv.exe has generated errors and will be closed by Windows.  You
will need to restart the program".<br>
<br>
If I turn off the layer that winds up missing on the map, everything
goes on fine,.<br>
<br>
Sad thing is I can't find anything in Apache's logs that will tell me
what's going on (all that's there are "Premature end of script headers:
mapserv.exe" entries), and mapserver isn't logging anything either. 
Also, running shp2img<br>
<br>
Here is the mapfile for the machine acting as WMS Server:<br>
