High Latency with service checks

[Yu Watanabe]

Hello All.

I would like to get an advice with nagios latency issue.

In nagios 3.0.6 with RHEL 4, would there be a possibility 
that service check latency hikes even though the sar or iostat
usage is not in relatively high load usage? (I am planning to upgrade to v 3.2.3 soon.)

SAR average cpu usage were 40% and iowait was lying 0%. Swaping were not occuring.

I have more than 1000 ping checks and average latency are 20 min. Check execution time for ping is
all below 1 sec. Plugin I am using is check_icmp. 

CPU I am using is ,
Intel(R) Xeon(TM) CPU 2.80GHz
Memory is 8GB
OS is RHEL 4.4

Are there any possiblity that Nagios gets locked up with the service check scheduling?

Thanks,
Yu
