Passive freshness checks go wrong

Hi,

I have a Nagios 3.2.3 box on an Ubuntu server 11.04 with about 930 hosts 
and 28500 services. For each host, I have 5 passive checks mapped on 
SNMP Traps. In order to secure those checks, I set up a freshness checks 
using check_dummy and a freshness threshold of 15min, as I normally 
receive traps every 10min.

When I added 5 hosts to Nagios, all my passive checks went progressively 
to a critical status saying that "return code of 127 is out of bound - 
plugin may be missing". I didn't touch my commands.cfg file nor my 
services files, I have only added 5 files to my hosts configuration 
directory and reloaded nagios.

Has somebody already seen that kind of behaviour?

Thanks in advance,

Marc-André
