Hi.

I decided to test this patch in my test enviroment against my configuration with 3000 hosts and 30000 services, but after patching nagios segfaults with

-snip
Starting network monitor: nagios
/etc/init.d/nagios: line 185:  4257 Segmentation fault      $NagiosBin
-v $NagiosCfgFile >/dev/null 2>&1
CONFIG ERROR!  Start aborted.  Check your Nagios configuration.
-snip

Of course, my configuration works with clean nagios 2.0 code.

Here is my steps

I downloaded nagios2b3
I patched it with: cat nagios_xng_patch_1.0 | patch -p1
./configure prefix=/opt/nagios/
Make all (no errors)
Make install (no errors)
 
My system is a 2x3Ghz Xeon on Debian Sarge with GCC 3.3.5
Attached is a strace dump of the nagios execution.



cheers
