<DIV dir=ltr><FONT face=Arial size=2>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.</FONT></DIV>

<P><FONT size=2>Regina,<BR><BR>Sorry about that. I guess I should have been clearer.<BR><BR>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.") <BR><BR>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. <BR><BR>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.<BR><BR>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. <BR><BR>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: <A href="http://dev.uai.com:28080/public/blur.html">http://dev.uai.com:28080/public/blur.html</A> 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?<BR><BR>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?<BR><BR>Thoughts?<BR>-LK<BR><BR><BR>________________________________<BR><BR>From: Obe, Regina [<A href="mailto:robe.dnd@cityofboston.gov">mailto:robe.dnd@cityofboston.gov</A>]<BR>Sent: Fri 1/18/2008 9:49 AM<BR>To: Lee Keel; users@openlayers.org<BR>Subject: RE: [OpenLayers-Users] Pink Tile Killing Me<BR><BR><BR><BR>Lee,<BR><BR>Are you saying the tile that doesn't work doesn't work when you call the<BR>url directly either or only when in OL.<BR><BR>If the bad url doesn't work outside of OL either, then did you try<BR>turning debug on on your mapserver file and see if it returns a more<BR>meaningful error?<BR><BR>The only difference I see between the 2 is the BBOXs are different but<BR>that could be just a difference in where you were clicking or it could<BR>be its out of range.<BR><BR>Other thought is there is no difference and OL is just requesting tiles<BR>faster than your server can deal with.<BR><BR>Hope that helps,<BR>Regina<BR><BR><BR><BR>-----Original Message-----<BR>From: users-bounces@openlayers.org [<A href="mailto:users-bounces@openlayers.org">mailto:users-bounces@openlayers.org</A>]<BR>On Behalf Of Lee Keel<BR>Sent: Friday, January 18, 2008 10:23 AM<BR>To: users@openlayers.org<BR>Subject: Re: [OpenLayers-Users] Pink Tile Killing Me<BR><BR>Hello all.
