[mapserver-users] WMS layers get canceled

[Puneet Kishor]

I am unable to figure this out --

My app front is Google Maps API v3 with MapServer 6.0.1

$./mapserv -v
MapServer version 6.0.1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=ICONV SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=GEOS INPUT=POSTGIS INPUT=GDAL INPUT=SHAPEFILE

The app fires WMS requests that look like so in Firebug and Safari Web Inspector (one per tile)

http://path/to/server/cgi-bin/app?version=1.1.1&request=GetMap&format=image/png&TRANSPARENT=TRUE&Styles=&SRS=EPSG:4326&Layers=lyr&width=256&height=256&BBOX=-135,40.97989806962013,-90,66.51326044311185

The status code in Firebug is "Aborted" ("Canceled" in Safari Web Inspector). The ms_error file kicks in the following messages --

[Thu Sep 22 21:00:55 2011].347078 msWMSLoadGetMapParams(): enabling non-square pixels.
[Thu Sep 22 21:00:55 2011].347608 msDrawMap(): kicking into non-square pixel preserving mode.
[Thu Sep 22 21:00:55 2011].347615 msDrawMap(): rendering using outputformat named png24 (AGG/PNG).

My .map file has the following incantation --

        #### in the MAP section #####
	PROJECTION
	  "init=epsg:4326"
	END
	WEB
	  METADATA
	    ows_enable_request "*"
            wms_abstract "blah blah"
            wms_accessconstraints "none"
            wms_title "gpsvecs"
            wms_onlineresource "http://path/to/server/cgi-bin/gpsvecs?"
            wms_srs "EPSG:4326"
            wms_keywordlist "foo,bar"
            wms_enable_request "*"
	  END
	END

        #### in the LAYER section ####
	LAYER
	  NAME "lyr"
          CONNECTION "host=localhost port=5432 dbname=db user=user password=passwd"
          CONNECTIONTYPE POSTGIS
          PROCESSING "CLOSE_CONNECTION=DEFER"
          DATA "the_geom FROM (SELECT gid, a, b, the_geom FROM table) foo USING UNIQUE gid USING srid=4326"
        
    	  PROJECTION
    	    "init=epsg:4326"
    	  END
    	
	  METADATA
	    wms_srs   "EPSG:4326"
	    wms_title "lyr"
            wms_abstract "blah blah"
            wms_keywordlist "foo,bar"
            wms_enable_request "*"
            wms_extent "-180 -90 180 90"
	  END


Suggestions?
