MapServer Application Error

[Stephen D. King]

Hi Nicolas,

Thanks for your reply.
The WMS server problem appears to have been caused by a layer having a
STATUS of DEFAULT in the map file; switching it to OFF has solved the issue.
Still having the memory problem unfortunately!

Application Error


Hi Stephen,

I also got this error with Oracle Spatial error..sometimes.  I didn't find
the reason yet though...
Running Windows 2000 with IIS.

For your second prob, try just setting the missing layer on and the others
off to see if it will appear alone.  Perhaps it's just a bad layer
ordering...

Hi,
I've been setting up a test application using MapServer 4.4.1 on a Windows
XP Professional machine with IIS. Everything works fairly well apart from an
occaisional mapserv.exe - Application Error box that appears with a message
such as:

The instruction at "0x7c93426d" referenced memory at "0x00000000". The
memory could not be "read". Click on OK to terminate the program. Click on
CANCEL to debug the program.

My application currently has 7 layers, six of which are vector and one
raster (ECW format). Originally I had more raster layers, and I thought that
this was causing the problem, however, even without them I still have this
problem. Sometimes the error also causes images in the legend not to be
written correctly.

On another, perhaps related note, I have set the application up as a WMS
server. I can access this through ArcGIS 9, however, it will not display all
7 layers at the same time, rather only six are visible in the map, even if
all seven are switched on.

Would be grateful if anyone can give me an idea what this problem is.

Many thanks,
Stephen
