After checking the apache error log we also get:<br>
<br>
[Thu Jul 13 10:22:02 2006] [notice] child pid 9429 exit signal
Segmentation fault (11)<br>
<br>
We are using mapserver 4.8.3, php 4.3.10 and apache 2.0.53 running on a
Suse 10 box.<br>
<br>
The mapscript functions that seem to be in use when the crash is caused
are: queryByAttributes(), getResult() and getShape()<br>
<br>
should we list this as a bug on Bugzilla?<br>
<br>
Thanks<br>

We are having (and have had for while_ this problem - and it does seem
reasonably random.<br>
<br>
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.<br>
<br>
Anyone got any ideas?<br>

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? <br>

<br>
As we can see a lot of people are suffering from this but no one seems<br>
to have any solutions. Does this only appear with php mapscript? Is<br>
this a bug? A known bug? Is there a solutions? This is a fatal error <br>
since this kind of behavior avoids us to use php mapscript in<br>
production, in case this is a php mapscript issue as it seems to be.<br>
