Hi Jeremy, A health FastCGI process have a lifetime, so the PIDs of all php-cgi processes should in a short range. There are some 'php-cgi' fall in 'sbwait' state, and stay there forever. The frozen 'php-cgi' can't accept new request, so never retire. Please forgive my poor English. 2008/11/7 Jeremy Chadwick <koitsu@freebsd.org> > On Fri, Nov 07, 2008 at 07:29:37PM +0800, Ken Chen wrote: > > Hello, > > > > I have 4 web servers with lighttpd to serve one web site with DNS load > > sharing.
