Steve -
 
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

Hi All,

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 fine.....

Weird eh?  Any suggestions much appreciated!

Thanks,
Steve H
