AW: RE : Re: [Nagios-devel] webinterface don't works with large number of hosts in Nagios 2.0 current cvs version

[Hildenbrand, Marcus]

Hi,
 
I checked this with the CVS version from 13/July with the follwing header in xdata/xodtemplate.c
 
 /*****************************************************************************

Should be good enough.
 
Regards
Marcus Hildenbrand

	The test for strlen(input)>MAX_XODTEMPLATE_INPUT_BUFFER has been removed on 05/25/2005 from xodtemplate_add_object_property() in the CVS version. Maybe you could try the current CVS.
