Service Check Timed Out

Hello,
this is the error i see in the cgi web interface.
in the error log i see stuff like:
SERVICE NOTIFICATION:
noc;host-aaa;FPING;CRITICAL;notify-by-email;(Service Check Timed Out)
SERVICE ALERT: host-bbb;FPING;CRITICAL;HARD;3;(Service Check Timed Out)
SERVICE ALERT: host-ccc;FPING;CRITICAL;SOFT;1;(Service Check Timed Out)
The FPING service is a perl script i wrote wich does a fping, and a
snmpwalk. In the worst case scenario this should take are 30 seconds to run.
I've set up service_check_timeout=90 in the main (nagios.cfg) config file.
The machine is under medium to heavy load, but i can't understand why
it's getting a timeout, as 90 seconds seem more than enough for any of
the scripts to run.
Is there any possibility that this is generated by the check-host-alive
plugin and it escalates ? or something like that ... ?
The nagios configuration is pretty simple, some of the more important
things are:
====================================
inter_check_delay_method=s
service_interleave_factor=s
max_concurrent_checks=0
service_reaper_frequency=10
service_check_timeout=90
host_check_timeout=90
event_handler_timeout=30
notification_timeout=30
ocsp_timeout=15
perfdata_timeout=15
check_for_orphaned_services=0
check_service_freshness=1
freshness_check_interval=60
==================================
The service template is:
==================================
define service{
name generic-ping2
active_checks_enabled 1
passive_checks_enabled 1
parallelize_check 1
obsess_over_service 1
check_freshness 0
notifications_enabled 1
event_handler_enabled 1
flap_detection_enabled 1
process_perf_data 1
retain_status_information 1
retain_nonstatus_information 1
service_description FPING
is_volatile 0
check_period 24x7
max_check_attempts 3
normal_check_interval 5
retry_check_interval 1
contact_groups noc-acm
notification_interval 1800
notification_period 24x7
notification_options c,r
register 0
}
====================================
any ideeas ?
