Hi Jasmine,
we have the same SERVICE UNKNOWN when i tried to get some information with check_snmp. SNMP is UDP, so the host i'm looking at doesn't have to answer, 
because there is no session SYN, SYN-ACK,FIN. In our environment this happend 
a lot time of the day, i tried with 20 checks an retry-checks.
Your Question, what happens between 8:06 and 8:34,  does nagios schedule a service-check between this time? You can find out in the service-detailed information where you can find

Last Check Time:				20-03-2003 13:05:53
Status Data Age:				0d 0h 5m 13s
Next Scheduled Active Check:  20-03-2003 13:10:53
Latency:						< 1 second
Check Duration:				4 seconds
Last State Change:			20-03-2003 11:21:10
Current State Duration: 		0d 1h 49m 56s

Hope this helps
