Hi Steve, There's one symbol combination that I know needs to be looked at. I've been meaning to drop a note to the list about this.
Line features, or outlines of polygons: - symbolized using a cartoline symbol - with ANTIALIAS TRUE set within the Style object of the layer class being drawn with the cartoline symbol (not within the symbol definition, I haven't tried it that way). The documentation does not explicitly state not to use antialias in this situation. This symbolization combination has caused: - some of the infamous random CGI errors back to at least MapServer 4.6. - random failure of map images created in mode=map such as static maps generated using a mapserver URL in the SRC of an HTML IMG tag, this goes back to MapServer 4.4. - failure of HTML legend templates to be processed / added to your web page when the offending layers are turned on, back to MapServer 4.6. Some time ago I filed a bug on the third item, but it was only just recently with the release of mapserver 4.8.1 that I finally realized that this one mistake in my syntax was causing all the above problems. Symbolizing lines this way in older versions of mapserver actually worked producing nice results. The random nature of the failures just left me guessing after upgrading through 4.4 to 4.6 until 4.8.1 came out. MapServer 4.8.1 seems to be more strict (or sensitive) to this syntax mistake, and crashes giving the CGI error far more consistently, which finally allowed me to isolate the problem I was having with certain map layers. Removing my improper use of antialias ended all the above problems. I run MapServer as a Windows CGI, through IIS, on Windows XP Pro SP2 and Windows Server 2003.
