Mark,
Could this be a timeout issue?
What happens if the user right clicks on the pink tile in FF and selects
View Image? or Reload Image?
Do you have some kind of max memory limit or ulimit set?
Or a long running process killer?

Hello,
I received a report that a GeoMOOSE / Mapserver web mapping application
http://geomoose.lyonco.org/MurrayMoose/
<http://geomoose.lyonco.org/MurrayMoose/> is creating pink tiles when
zoomed out. I found out that the user has a very large monitor, so I
thought that I may have forgot to set the MAP MAXSIZE parameter. That
was not the issue.
Next, The user then reported that the pink screen only was present when
boundary>municipal layer was turned on. This particular layer is part of
a mapfile that contains several layers. All of the other layers are
working fine. Also when he zooms into the map the layer appears on his
application as expected. So I thought that the issue has to be with the
layers* within the mapfile.
*The municipal boundary layer in GeoMOOSE is tied to the Townships and
CityLimits layer in a single map file.
The layer file itself is a generic template that I have been using for
several different applications without complaint. I also tested the
application on my computer using a variety of browsers including IE8,
which is the browser the user reported that he was having trouble with
the pink screens. I also adjusted the browser size to make it the
requested image larger, zoomed in and out, and I have not had any trouble.
I included a part of my map file as well as a log file from what I think
is a unsuccessful request and a successful request from the same user.
