This is a stock Centos5 install 5.0.0.el5.centos.2 with 2.6.18-8.el5.
Single processor 2 GB ram dell box. 

Anything else I can dig into for you? I was thinking of pulling down
3.0b5 and seeing if I have the same issue (if that helps/make sense?).

3.0b6 was configured with: 

/configure --prefix=/usr/local/nagios --with-cgiurl=/nagios/cgi-bin
--with-htmurl=/nagios -with-command-group=nagcmd
--with-htppd-conf=/usr/local/apache2/conf/ --enable-perlcache
--enable-embedded-perl --disable-statusmap
