Hi,

i have nagios-3.0b3 running for 7 days now with around 350 checks and
around 40 hosts. No problems with CPU-load etc. I only have high cpu-load
produced by mysqld if i restart nagios and ndoutisl trys
truncating/cleaning my database... That is the only problem i can see...

kind regards, dennis
