I'm not sure if this is it, but a number of years ago, I had a PC
running a RIP application give similar results. It turned out to
be a bad external cache chip. It still baffles me as to why it only
affected image data, and not crash the computer.

Thanks in advance,

strange...
what version of mapserver are you using?
can you (temporarily) turn off the angle follow of your labels and
report if you're still having the same output problems

Lee -
INTERLACE=ON is not "wrong". Tim is pointing out that if you're viewing an interlaced
output image, the first, alternating set of scanlines will be displayed and then your browser will
start again at the top of the image, filling in the alternate interlacing lines. This will cause
the top of the image to appear complete while the bottom is "blurry". You can see
variations on these visual artifacts depending on your browser, and the effect is more pronounced
over a slow connection.
But if the image still looks blurry at the bottom even after you're certain the
image has been completely loaded, then this is not your problem.
It's hard to diagnose visual problems in text; can you either post the output
image or (preferably) a public URL where the image can be viewed?

One quick thought that I have since you say that a layer image is
blurred on the bottom portion is that you have FORMATOPTION INTERLACE=ON
set. This turns on interlacing and sometimes I see that it takes a few
seconds on my mapserver to fully render the image. If you want to
prevent this blurring turn that setting off in your Mapfile.

Subject: [UMN_MAPSERVER-USERS] mapserver error
Hello list. I am having a problem and it is beginning to look like
mapserver is behind it somehow. I am using ms4w 2.2.6 to render
postgres data to openlayers. Mapserver is configured to use IIS\CGI
instead of apache. I am actually having 2 problems, but I am not sure
that they are not related. One problem is that sometimes the server
just isn't returning any data for different layers to OpenLayers. I
have talked extensively with the OL guys and have come back to the fact
that if I take the URL that is requesting the information from
mapserver, then I get: "The specified CGI application misbehaved by not
returning a complete set of HTTP headers." The most consistent way I
can reproduce this is to zoom in real close. The second problem I am
having is that when I am getting layer images back, they are blurred on
the bottom portion. It looks like someone took a cloth and just wiped a
whiteboard.
I am about 5 days late on a deadline to have this up and running, so I
am open to try any suggestions that someone may have.
Thanks in advance,
Lee
