[UMN_MAPSERVER-USERS] Strange map draw issue

[Steve Hall]

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 : http://demo.mercatorgeosystems.co.uk/tmp/1158239461914994.png 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
