[mapserver-users] Apache crash using Mapserver with big mapfile (about 2500 lines)

Thu May 7 00:48:00 PDT 2009

Dear users,

I’m using the following environment:
Ubuntu 6.06 (libc6 2.3.6)
Apache 2.2.9
Php 4.4.2
Mapserver 4.8.2
Maplab 2.2.1 (last available version)

Using a project inside Maplab/gmapfactory with a big mapfile (about 2500 lines) the httpd process of Apache crash.
Enclosed you can find the details of the crash (Backtrace/Memory map).
Apache compilation details:
./configure --prefix=/usr/local/apache229 --enable-info --enable-mime-magic --enable-rewrite --enable-so --enable-speling --enable-unique_id --enable-usertrack --with-mpm=prefork
PHP compilation details:
./configure --enable-kbmmw --with-regex=system --with-freetype --with-dbase --prefix=/usr/local/apache229/php --with-mysql=/usr/local/mysql4115 --with-pgsql=shared,/usr/local/pgsql8014 --with-pdflib=shared,/usr/local/pdflite703 --with-config-file-path=/usr/local/apache229/php --with-png --with-jpeg --with-jpeg-dir=/usr/local --with-tiff --with-gd --with-zlib --enable-track-vars --enable-sockets --enable-wddx=shared --with-xmlrpc=shared --enable-calendar --with-iconv=/usr/local/libiconv112 --with-iconv-dir=/usr/local/libiconv112 --with-apxs2=/usr/local/apache229/bin/apxs --enable-cgi
Mapserver compilation details:
./configure --enable-debug --with-proj=/usr/local --with-ogr=/usr/local/bin/gdal-config --with-gdal=/usr/local/bin/gdal-config --with-gd --with-httpd=/usr/local/apache229/bin/httpd --with-php=/usr/local/apache229/php --with-php-regex-dir=/usr/local/apache229/php/regex --enable-runpath --enable-force-freetype1 --with-wmsclient --with-freetype --with-png=/usr/local --with-jpeg=/usr/local --with-libiconv=/usr/local --with-wfs --with-wfsclient --with-postgis=/usr/local/pgsql8014/bin/pg_config

I tried to upgrade the OS version (Ubuntu 7.04 – libc6 2.5.0), but the result doesn’t change.
I tried also to compile different SW versions (Apache 1.3.41, Php 4.4.9, Mapserver 4.8.3 & 4.8.4), but the result doesn’t change

Many thanks,
Edgardo
