Huge Service Latencies

[Eli Stair]

Just for comparison, I'm having a very similar issue.  Currently it's 
better, but latency last week was around the same area.  I'm running 
with the perlcache, most checks are quick SNMP gets.  System is a dual 
Opteron 246, 4GB RAM and currently doing nothing but this.

Check Execution Time:  	0.02 sec	30.02 sec	6.020 sec
Check Latency:	0.09 sec	79.02 sec	69.122 sec
Percent State Change:	0.00%	15.86%	0.03%

PS - I'm moving the SNMP checks to Cacti, and pulling them with 
check_rrd_data.pl due to the huge delay (and load) in the perl wrapper 
to snmpwalk.
