[OpenLayers-Users] Pink Tile Killing Me

I suppose to rule out restriction on server as the issue, you could run the same configuration on a local server you have full control over if that is possible.
The only thought I can think of if it is a restriction issue - is that map server is generating the image fine and its in the outputting of the file where there is a problem, like because of the CGI restrictions on the server, if the file exceeds a certain size - it kills the process.
Why is your sample blur image a bmp file? I presume you are not dishing out bmps.
Hope that helps,
Regina

Regina,
Sorry about that. I guess I should have been clearer.
If the layer is not displayed in OL, then I get the URL that the layer is suppose to represent and paste it in a new window and I get error that was below it (502: "The specified CGI application misbehaved by not returning a complete set of HTTP headers.")
I have set DEBUG 5 in my mapfile, but this is all I am getting. I look in my log file that the map file is pointing to and I get "......, normal execution" for each call.
The change in BBOX is because i zoomed out in OL. It seems that on a couple of the layers, they work until I zoom in to a certain level. And yet others do not work at any level. And yet even others work at all levels. I have made 2 line layers the same in the map file (where 1 works and the other does not), and still get the same results.
I have thought about the chance that OL is requesting the tiles faster than server can produce, but the URL to the image doesn't work either. So I am leaning away from it being something directly in OL.
On another note, there is one more thing. Once I do get the layer back there is a blur in it. You can see a cut of this blur at: http://dev.uai.com:28080/public/blur.html This happens on every WMS layer that I get back. But again, if I take the URL for that layer and paste into another window, then the image that I get back also has the blur. So that means it is coming from mapserver that way, right?
Let me just throw out that this client is very strict with permissions and network. Can anyone think of a permission or network setting that might cause something like this?
Thoughts?

Lee,
Are you saying the tile that doesn't work doesn't work when you call the
url directly either or only when in OL.
If the bad url doesn't work outside of OL either, then did you try
turning debug on on your mapserver file and see if it returns a more
meaningful error?
The only difference I see between the 2 is the BBOXs are different but
that could be just a difference in where you were clicking or it could
be its out of range.
Other thought is there is no difference and OL is just requesting tiles
faster than your server can deal with.
Hope that helps,
Regina

Hello all. I have been working with the mapserver list still trying to
figure out this problem. Here is where I am at and I am hoping some one
can help.
If I use
http://webserver/cgi-bin/mapserv.exe?map=/mapserver/pc/gas.map&layers=ba
semap+basemap_anno
<http://webserver/cgi-bin/mapserv.exe?map=/mapserver/pc/gas.map&layers=b
asemap+basemap_anno> ) then all of my layers seem to be working at any
zoom level. But if I go to my openlayers application, they don't always
work. If you get a layer not working in the OL app and check the URL,
it doesn't seem to be incorrect. So what is the difference between OL
requesting from mapserver based on a bbox and the HTML below requesting
an image from mapserver?
Thanks,
LK

To add to what Chris said. If you right click on the image and choose
properties and then copy the url and paste it into a new browser window
-
what happens - do you get an error returned or an image?. That will
allow
you to test it outside openlayers and determine if it is a mapserver
problem.
