Re: [UMN_MAPSERVER-USERS] Mapserver returns blank pages

[Stuart Eve]

After checking the apache error log we also get: [Thu Jul 13 10:22:02 2006] [notice] child pid 9429 exit signal Segmentation fault (11) We are using mapserver 4.8.3, php 4.3.10 and apache 2.0.53 running on a Suse 10 box. The mapscript functions that seem to be in use when the crash is caused are: queryByAttributes(), getResult() and getShape() should we list this as a bug on Bugzilla? Thanks Stuart Stuart Eve wrote: We are having (and have had for while_ this problem - and it does seem reasonably random. The main trouble is that I don't know how to get php to spew out the error - and instead it just returns this blank screen, instead of returning the error as it does normally. I had first thought that it was because I was using php mapscript and had nested functions - but it seems like lots of people are coming up with the same thing. Anyone got any ideas? Matthew Kane wrote: I wasn't actually using php mapscript in the mapfile that gave me segmentation faults. Strangely, I got the map to display on a Sun machine if I removed all references to true-type fonts and relied only on bitmap fonts for my labels. Even more strange is that when I moved the same file to a red hat server, mapserver simply hangs. No error message in either the browser or the apache error logs, just hanging. The same thing happened when I tried running the mapfile with shp2img. Has anyone else experienced this problem? Could this be a bug in one of the third party libraries that mapserver relies on? Or more likely a problem in how we code our mapfiles? Thanks, Matt On 7/12/06, antti siukola <[EMAIL PROTECTED]> wrote: Hi! As we can see a lot of people are suffering from this but no one seems to have any solutions. Does this only appear with php mapscript? Is this a bug? A known bug? Is there a solutions? This is a fatal error since this kind of behavior avoids us to use php mapscript in production, in case this is a php mapscript issue as it seems to be.
