It seems icinga will only allow me to have x amount of services defined in a service group. Once I reach x the plugin returns a Code 127.
Below is my config. in order to make things work all I have to do is comment out the service group definition and things start working.

I want to say that x was 3265 have to double check.

On that flip side I cannot get nagios to do more than 1200 services in a service group and on Nagios a hostgoup of 7661 causes the code 127 while dropping the group down 500 clears the 127.

Are there limit to number of services and host in a group? If so what is the magic number and why?

define command{
command_name sysUpTime-test
command_line /usr/local/icinga/libexec/check_snmp -C $_HOSTCOMMUNITY_STRING$ -P 1 -H $HOSTADDRESS$ -o .1.3.6.1.2.1.1.3.0

}
define service{
use WAP-svc-T ; template
hostgroup_name HW.Foundry.IP-250
# servicegroups system.sysUpTime.IP250
service_description system.sysUpTime
normal_check_interval 60 ; when in normal state, check every n minutes
check_command sysUpTime-test
notes .iso.org.dod.internet.mgmt.mib-2.system.sysUpTime
}

I had a look on the code and the only obvious thing that could go wrong here is some malloc failure. Is this a 32bit system? How big is the process?

Ok I did a couple of tests with a servicegroup of 4000 services. I can not see any Problems. Also the desrciption is somewhat unclear first you say problems occur if you have more then 3265 services in a group later you say you cannot put more then 1200 services in a service group. And to confuse some more you talk about hostgroups. So please give more precise details what the problem is and how to reproduce it.

i don't really get the problem. plugins, nagios, icinga, configs - what exactly is wrong?

I was about to close that one to. The report is not clear on what actually is wrong, tests are ok and no further feedback.

Just a note:

Host||Servicegroups are just configuration items without big function at all, except inheritance or the view side like CGIs or other Webstuff.

In no-way that configurationgroups are doing anything with executing checks.

The mention error like 127 xxx (possibly "Plugin may be missing") results after a "reload" and inpropper permissions on ressource.cfg which may not be readably by icinga user.
