Mapscript c# problems and apache2 scratches

Mon Jun 26 11:39:45 EDT 2006

HI

New problem with the mapscript c# library.
I'm doing a web site using, among others, querybyshape function. If there
are several requests using this function i scratches the server

My configuration is the following

Mono (1.1.13)
gtk 2.8
Apache (2.2.?) with de mod_mono compiled for it mod_mono 1.1.14 MApscript
(4.8.3). 
Postgres 8.1.3 and Postgis 1.1.1
GDAL 1.3.1
Ming 0.30
Proj4 (4.4.9)
Libiconv 1.9.1
gd-2.0.33

All these programs has been compiler on the computer

Mapserver has been compiled with the configure : 

./configure --with-gdal=/usr/local/bin/gdal-config
--with-ogr=/usr/local/bin/gdal-config
--with-postgis=/usr/local/pgsql/bin/pg_config --with-ming --with-png
--with-jpeg --with-zlib --with-tiff --with-gif --with-proj
--with-gd=/usr/local --with-httpd=/usr/sbin/httpd2

The apache error_log file can contain the following errors

=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.
