Yes, but the contacts know that the server is down so the services are =
down too. When I know that the server is down, I don't care about =
services for the moment. I don't think I've got service that can be up =
when host is unreachable. I think I'll make the change and test it. This =
can help me to see only few errors, but real errors (so when the service =
is down, it's not about unreachability, but the service is really down).

Yes, I think about patch the :
temp_service->last_hard_state=3Dtemp_service->current_state;
into:
temp_service->last_hard_state=3DSTATE_UNKNOWN;

in the function reap_service_checks, line 1183 (Nagios 2.5)


Thanks for the help,

I'll be back with test soon.
