Dear List, we're kind of stuck with the following problem:
First of all we are running Mapserver 5.6.5 in CGI Mode on Windows 2003 Server (64bit). Webserver is Apache 2.2. We have a large Mapfile (seperated into 5 different parts using INCLUDE) with a total of 571 Layers. The layers have different MAXSCALEDENOM values so not all of them are drawn at all scales. The layers are referencing the DATA via TILEINDEX (it's S-57 data read through OGR). Most of the layers cover only a small area, so if I zoom in to the map more and more layers must be taken into account of drawing but only a small number must be drawn. All of the layers are divided into three groups using the GROUP parameter. What happens if I zoom in to the map at some point mapserver crashes (actually it's not crashing it just stucks). If I reduce the total number of layers (by commenting out parts of the mapfile) the map will be drawn again. So my guess is that there is a problem with the number of layers (or styles?, or symbols?, or number of layers per group?) included. I turned on debugging on all of my layers but that didn't helped. If I check the taskmanager mapserver.exe goes to 100% cpu usage and goes back to zero after a few seconds but it's not being terminated. It's still running in the process list. Debug output stops right in the middle of the line. No error message is send to the client or written to any of the logfiles. Actually no response is send to the client at all. If I terminate the process using the task manager "Premature end of script headers: mapserv.exe" is written to the apache error.log and the client shows "Internal Server Error". Right know we have no idea of what to look at. If anybody has any hint what might goes wrong we maybe would be able to look at it and maybe fix it. But right now we're stuck.
