getFeatureInfo problem

[Jan Jansen]

Hello list, 

I have a problem with the WMS getFeatureInfo command. I have an Oracle Spatial POINT Layer.
GetFeatureInfo works fine, but when I zoom in to a certain scale, the request doesn't return any results.

request:
http://his-kust.ontwikkel.gisinternet.nl/cgi-bin/mapserv?map=/home/geodata/project_data/his/mapfiles/his_server_mapbuilder.map&reeks_id=2&stormfilter=1&&VERSION=1.1.0&REQUEST=GetFeatureInfo&LAYERS=kustduinsig&SRS=EPSG:28992&BBOX=87127.77696385694,469462.49761573685,87895.82254419167,469994.2214790455&WIDTH=650&HEIGHT=450&INFO_FORMAT=text/html&FEATURE_COUNT=1&QUERY_LAYERS=kustduinsig&X=322&Y=220

Tolerance in mapfile is set to a high level (20).
The X Y pixel location is exactly on the point (cross checked it with the getMap request)

Any idea's?

Thanks in advance,

Kind regards, Jan Jansen
