[mapserver-users] Non stoping generation

[Nelson Branco]

Hi Alexandre,

the Web server I'am mentioning is the MapServer Web Server.

I can observe the mapserv process running by more than 5 minutes (of CPU 
time at 100%).

So, that doesn't seem to be the problem.

Thanks any way.

Meantime, I isolate the problem even more, I find that the "similiar" 
request direct to MapServer worked, the difference is that TileCache is 
configured do add a extent of 20px to eliminate miss match tile junctions.

However, the same request with that extra size direct to MapServer also 
run forever...

Here is the URLs:
    - Faling one with extent:
    http://127.0.0.1:8881/cgi-bin/mapserv.exe?map=mapfile.map
        &transparent=true
        &layers=mylayer
        &styles=
        &service=WMS
        &width=552
        &format=image%2Fpng
        &request=GetMap
        &height=552
        &srs=epsg%3A900913
        &version=1.1.1
        
&bbox=-916644.789907%2C5099560.83129%2C-916315.155222%2C5099890.46597

    - Successful without extent:
    http://127.0.0.1:8881/cgi-bin/mapserv.exe?map=mapfile.map
        &transparent=false
        &layers=mylayer
        &styles=
        &service=WMS
        &width=512
        &format=image%2Fpng
        &request=GetMap
        &height=512
        &srs=epsg%3A900913
        &version=1.1.1
        
&bbox=-916632.846621%2C5099572.77457%2C-916327.098508%2C5099878.52268


Any more ideas?
