Trouble with passive checks and freshness

[Christopher Odenbach]

Hi,

we have the following setup:

Nagios 2.5
73 hosts
335 active checks
765 passive checks

Each host submits its passive check results every 5 minutes into the 
nagios command file. The freshness threshold is set to 2000 seconds,
so the service stays passive, when everything runs as it should.
The check_command is defined as check_dummy, which generates the
message "No data from host" when executed actively.

This works fine for nearly every host. But there is one host, which
is not different from the others, that makes trouble. The data is
coming in every 5 minutes, but Nagios keeps flipping between active
and passive mode:

root at giedi3[nagios]# tail -10000 nagios.log | grep rana | grep disk | naglog.pl  | cut -c-100

All other hosts work just fine:

root at giedi3[nagios]# tail -10000 nagios.log | grep etamin | grep disk | naglog.pl  | cut -c-100

[01.09. 13:34:54]  EXTERNAL COMMAND: PROCESS_SERVICE_CHECK_RESULT;etamin;Local disk;0;DISK OK - free

The configuration is:

define service {
        use                             check_local_disk_templ
        host_name                       rana
}
define service{
        use                             passive_templ
        name                            check_local_disk_templ
        service_description             Local disk
        servicegroups                   local-disk-services
        check_command                   check_disk!-w 15% -c 10% -x /afs -e
        notifications_enabled           1
        register                        0
}
define service{
        name                            passive_templ
        register                        0
        max_check_attempts              1
        normal_check_interval           10
        retry_check_interval            1
        active_checks_enabled           0
        passive_checks_enabled          1
        check_freshness                 1
        freshness_threshold             2000
        check_period                    always
        notification_interval           0
        notification_period             always
        notification_options            w,c,r,f
        notifications_enabled           0
        contact_groups                  Server
        process_perf_data               1
}
define command{
        command_name            check_disk
        command_line            $USER1$/check_dummy 3 "No data from host - nsce not running?"
}

Any ideas what is going wrong here? Why is Nagios flipping the
service to active when data has arrived less than 2000 seconds ago?

Thanks,

Christopher
