Strange map draw issue

Well, just about anything in California is a little odd.....
Are you saying that if you simply refresh the image and re-draw the
exact same map you'll see this line of text change? That's puzzling. I
would speculate that it's a (garbage) text label for some garbage
feature - there's some feature that's defective in both location and
label (attributes messed up) and that feature is being labeled.
The first thing I'd try is to eliminate layers from the image, testing
until the garbage goes away. That could identify the offending layer;
if there are multiple classes in that layer, use the same system to
identify which class it is. Then see if that says anything helpful.

Subject: [UMN_MAPSERVER-USERS] Strange map draw issue
I've been using Mapserver for a while now, in a variety of situations,
but am seeing a slightly strange behaviour in one of my setups.
Basically i'm getting a line of 'garbage' being drawn across the
generated map image.
A sample of what I mean is here :
There is no road feature or other line that should be there, and if I
redraw the map the line of garbage will either disappear or change in
either length or 'content'. It doesn't appear all the time, but
certainly enough to be annoying.
My MapServer version is 4.8.1, running with Apache 1.3.31 on Fedora Core
4. I've got several other MapServer based configurations on this setup
and they're all working fine. The data source in question is an Oracle
10g (10.1) database which is also used for other systems and seems
Weird eh? Any suggestions much appreciated!
