[UMN_MAPSERVER-USERS] Mapserver demo crash

Fri Aug 26 17:49:39 PDT 2005

Well, I was finally able to get the demo working. I had to remove two layers
from the map file to do so, but c'est la vie. If anyone could shed some
light on why this would make a difference, I'd certainly appreciate it (I
thought maybe a corrupt png file at first, but that doesn't appear to be the
case). Anyway, in case any other Windows users run into this problem,
removing the following layers from the itasca.map file got the demo working:

  LAYER
    NAME ctyrdln3_anno

  LAYER
    NAME majrdln3_anno

(For complete layer source, please refer to the itasca.map file included
with the demo.)

I've had slightly better luck with Win2k, but still can't get the
demo running. When I try to initialize the demo, filemon shows that
mapserv.exe is reporting success reading
C:\inetpub\wwwroot\workshop\symbols\ctyhwy.png, but
then immediately calls Dr. Watson to generate an event in the
application log and promptly times out. The error reported is as
follows:

Event Type: Information
Event Source: DrWatson
Event Category: None
Event ID: 4097
Date: 8/3/2005
Time: 4:32:48 PM
User: N/A
Computer: MGARRISH
Description:
The application, , generated an application error The error occurred on 
08/03/2005 @ 16:32:48.859 The exception generated was c0000005 at address 
77F8F281 (RtlpWaitForCriticalSection)

The only other suspicious thing I see is that before trying to open 
ctyhwy.png mapserv.exe tries and fails to open the location 
c:\usr\local\lib - which I assume is hard-coded into the executable, because 
I can't find that path anywhere in the demo files.

Does anyone know if the demo is backward compatible with older versions of 
mapserver? I'm running the 4.4.1 Windows binary, but grabbed the demo from 
the 4.6 release.
